Since its inception, chemical science has evolved from back-room apothecaries and botanicals to a full-fledged industry employing nearly 810,000 people, including in the pharmaceutical sector. As humans have gotten a better handle on the science of medicine, manufacturing standards have had to rise to keep up with them. When consumers take pills for medicinal purposes, it’s with the implicit understanding and trust that they’re not only getting what they’re told they’ve gotten, but that every step of the process has ensured a rigorous standard of chemical purity testing of the Active Pharmaceutical Ingredients (APIs). Over the years, governing bodies such as the WHO have created General Manufacturing Practices (GMP) for APIs. The API GMP allow every step of the process from receipt of material to distribution to undergo the same GMP quality control.Read more

Chemical manufacturing, particularly when it comes to drug research and pharmaceuticals, is one of the larger industries within the United States. However, most people across the country don’t fully understand many of the basic principles of this field, despite how often they’re used by chemical manufacturers for scientific research and study. Radiolabeling, for example, remains a mystery to many people outside of the industry. So how does radiolabeling work? What are radiolabeled compounds used for?Read more
Did you know that a fume hood in a laboratory has to be checked at a minimum once a year by a certifier that is independent to ensure that it has the correct airflow that meets CAL/OSHA standards? Whether it’s in a GMP API manufacturing lab or chemical manufacturers, these standards have to be met in every lab and cleanroom.Read more
Chemical substances go through a long process before commercial use, and it’s essential that all steps are followed in order to meet GMP standards. From checking for chemical purity, handling substances, and maintaining a cleanroom, chemical handlers, such as pharmacies, should oblige to all set standards.
Pharmaceutical clean room standards meet good manufacturing practice (GMP) requirements. Clean room standards do not apply to non-sterilized items; however, for sterilized products, clean rooms are required. Even non-“clean” rooms are well ventilated and filtered. And, monitoring and maintaining a pharmaceutical clean room’s humidity–measuring plus or minus 1%–is standard when using state-of-the-art electronic sensing devices. Let’s look at the specifications of a clean room.
When it comes to testing the purity of chemicals for various applications in the medical and pharmaceutical community, the right testing matters. You want to be compliant with all laws and regulations of the company, whether your company is mostly into the lab work of most projects or you’re involved in the final completion of products and medical services, chemicals in the air can pose a safety risk and hazard. You can also be in health violation if chemical purity is not up to par.
Laboratories often replace their fume hoods for one main purpose: old age. The replacement process is something that is a concern of around 20% of laboratory owners and a third of the fume hoods replaced are old and outdated. You don’t want to put your lab technicians or other professionals at risk of injury or inhaling potentially harmful fumes, so you should consider assessing chemical purity in your establishment. Here are reasons why this matters, even if you feel like you are already abiding by all guidelines.
Your Labs May Not Be As Safe As You Think
While you have never had any quality control issues before when you do your regular routine of assessing chemical purity, you still don’t know if you are up to code with everything. GMP quality assurance is essential to operating a safe and legal laboratory so you should have the chemicals tested and have air quality assessed on the regular. This can be done in accordance with the recommendations of your quality specialist, or you can do this measure as recommended by your local state laws.
Your Labs Get Fully Tested for Quality
The best way to ensure the safety of your establishment is to have records that you work hard to keep your laboratory updated and sound. When you work with a variety of different chemical manufacturers and want to make sure you aren’t imposing on chemical purity in any way, you can help make your establishment more attractive for research and testing purposes. Universities, independent pharmacies, and other establishments may see your company in a better light and extend their service needs to your lab over others in your community.
However you want to improve the safety of your laboratory, you can do so by having your chemical purity tests done on the regular. Your specialist will be able to give you what you need for accurately assessing chemical purity in your office, labs, pharmaceutical sectors, and more.
Over the years, the pharmaceutical industry has grown in leaps and bounds. Today, they have been able to formulate high-quality drugs to eradicate some of the deadliest diseases in the world and control the rest. The acceptability and efficacy of these drugs is reliant on the purity of the chemical substances used for medicinal effect also known as active pharmaceutical ingredients (APIs).
The United States stands as the largest chemical producer in the world. However, the accolades should be directed to the chemical manufacturers who are involved in mixing these chemicals and coming out with a particular chemical that is used for a particular role. These manufacturers are always involved in a hard and complex task of determining chemical purity. It’s important to highlight that an impure chemical could have devastating impacts on the users, especially in the medical sector, where people use chemicals for medical purposes. But how do chemical manufacturers assess purity?
Assessing chemical purity is a complex task that involves incorporation of several styles and techniques that will give clear information on the composition of a particular chemical. The most important activity in determining chemical purity is understanding the specific components of a particular chemical and its physical or chemical properties. Some of the strategies used by chemical manufacturers to determine the purity of chemicals have been discussed below.
1. Use of Radiolabeled compounds
Radiolabeled compounds are carbon compounds that are used in chemical and biochemical processes of understanding the chemical constituents of a particular compound. Radiolabeled compounds are mostly used in the drug development stage and help in highlighting the compound formed after two or more molecules combine. Therefore, in a chemical process, radiolabeled compounds will be very useful in highlighting the physical and chemical properties of a particular product that has resulted after two or more chemicals combine. It is important to highlight that drug manufacturers know drugs by assessing physical and chemical properties.
2. Physical Comparison with Pure Standard
Physical comparison has been used in understanding the purity of a particular compound. It is the simplest method of checking purity as it only involves comparing a particular chemical with a certified pure sample. There is an argument against the use of physical comparison, but it is obvious that this method can show significant differences between products. Physical comparison is very useful in revealing large impurities such as colored impurities and dirt. Smell tests will also reveal the differences between the chemical undergoing tests and the actual and pure state of a particular compound. However, it’s important to note that only non-toxic chemicals can be tested through touch, taste, and smell.
3. Boiling and Melting Point Determination
It is obvious that the physical properties of a chemical can be used to indicate whether it is pure or not. Most of the chemical products have defined boiling and melting points. Pure chemicals are known to boil and melt at specific temperatures, and that is documented. However, if the melting point of a particular chemical is lowered, there is a great sense that the chemical is not pure. The boiling point will be higher than normal. This is a simple method of determining the purity of a product and is highly applied in various chemical manufacturing plants.
4. Colorimetric Methods
The colorimetric method is another widely used strategy of determining the purity of a chemical compound. Biochemically, some chemical compounds change into a particular color when they are exposed to a certain chemical. This is widely known, documented, and used as a standard way of determining the purity of various products. One of the major applications of the colorimetric method is in determining the presence of specific illegal drugs such as cocaine and heroin. Colorimetric purity testing is highly preferred because it does not only indicate the purity of a chemical but also the percentage purity.
5. Analytical Testing
Although other methods of testing purity are highly appropriate and advanced, analytical testing is the most accurate and highly preferred method of testing chemical purity. Analytical testing involves a standard procedure that is used in testing various chemicals. These procedures are applied in drug and chemical industries, and they indicate the presence and the number of impurities. Some of the analytical purity testing methods include titration, infrared spectroscopy, paper chromatography, and optical rotation, among others.
These are some of the strategies used in testing the presence of impurities in chemical compounds. However, the method that one applies depends on the resources available, the magnitude of the entire process, and the chemical under consideration. However, any method is likely to indicate the presence of impurities in a particular chemical.
