What Are Pharmaceutical Intermediates?
Published 2025-02-04
Intermediates are the isolated compounds produced on the way from starting material to active pharmaceutical ingredient.
A pharmaceutical intermediate is any isolated compound produced during the synthesis of an active pharmaceutical ingredient. Intermediates carry defined specifications for identity, purity and impurity profile because those attributes propagate to the final API. Reliable intermediate supply, with documented analytical data, is one of the main determinants of programme timelines.
