Compendial testing verifies pharmaceutical and biologic drug substances and products against recognized pharmacopeial standards, including USP-NF, European Pharmacopoeia, Japanese Pharmacopoeia and British Pharmacopoeia.
Bringing pharmaceutical and biologic products to market depends on consistent, pharmacopeia-aligned testing at every stage of development and manufacturing. Aligning to multiple compendial standards while meeting method transfer, batch release, stability and process validation timelines adds complexity to drug substance and drug product testing programs.
We provide routine physicochemical, microbiological and analytical testing for pharmaceutical and biologic drug substances and finished products, performed in accordance with USP-NF, European Pharmacopoeia (Ph. Eur.), Japanese Pharmacopoeia (JP), British Pharmacopoeia (BP) and client-specific specifications, supporting your product from early development to commercial manufacturing.
