Chemical Structure

Darunavir Impurity 19 CAS 1932353-11-1 chemical structure

Description

CATO manufactures Darunavir Impurity 19 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

CATO supplies Darunavir Impurity 19 (CAS 1932353-11-1), a pharmacopoeial impurity reference standard (molecular formula C7H10O4, MW 158.15 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Darunavir Impurity 19 (C7H10O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 158.15 g/mol, it falls into the medium-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.
