Chemical Structure

Felodipine Impurity 16 CAS 52334-51-7 chemical structure

Description

As a certified reference material (CRM), Felodipine Impurity 16 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

CATO supplies Felodipine Impurity 16 (CAS 52334-51-7), a pharmacopoeial impurity reference standard (molecular formula C6H8N2O, MW 124.14 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Felodipine Impurity 16 (C6H8N2O) contains an amide group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 124.14 g/mol, it falls into the low-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
