Chemical Structure

Perindopril Impurity 32 CAS CATO-C4X-125232 chemical structure

Description

CATO supplies Perindopril Impurity 32 (CAS CATO-C4X-125232), a pharmacopoeial impurity reference standard (molecular formula C11H21NO4, MW 231.29 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Perindopril Impurity 32 (C11H21NO4) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 231.29 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

As a certified reference material (CRM), Perindopril Impurity 32 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.
