Custom Non-GMP Isotopically Labeled Compounds

Moravek routinely carries out custom manufacturing of non-GMP compounds labeled with radioisotopes (carbon-14 and tritium) as well as compounds labeled with stable isotopes (primarily carbon-13, deuterium, and nitrogen-15). Our chemists are proficient in a wide variety of synthetic techniques and are able to prepare nearly any compound, including all U.S. Drug Enforcement Administration (DEA) Schedule I – V controlled substances. Once the synthesis is complete, our talented purification and analytical chemists will ensure that your compound meets agreed-upon specifications.
