GMP [3H] API Manufacturing and Purification

Licensed by the Food and Drug Branch of the California Department of Public Health, Moravek is permitted to prepare 3H label APIs for clinical trials and handle schedule I-V classified compounds under DEA authority.


GMP 3H API Manufacturing and Purification

Our GMP 3H API manufacturing and purification services include the preparation of 3H radiolabeled APIs for Phases 0, I, and II mass balance and microdosing (Phase 0 and Phase I) studies. We also perform GMP testing, synthesis, purification, and QA release in compliance with FDA Phase 0, I, and II GMP guidance (ICH Q7 Section XIX).

In the GMP 3H API process, radiolabeled APIs that have been produced or purified under GMP conditions are carefully examined on qualified analytical instrumentation. These APIs are also supplied with a complete batch record that includes documentation of the synthetic, purification, and analytical processes from start to finish. Finished 3H radiolabeled APIs can be sent to a contract research laboratory (CRO) to undergo preparation for investigational medicinal products (IMPs).

All of our work, from GMP testing to QA release, is carried out in 1 of our 4 certified GMP suites. APIs are analyzed using qualified HPLC and MS instrumentation and NMR.

Production of APIs includes, but is not limited to:
