Chemical Structure

Perindopril Impurity 91 CAS CATO-C4X-125291 chemical structure

Description

Perindopril Impurity 91 (C5H10ClNOHCl) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

CATO supplies Perindopril Impurity 91 (CAS CATO-C4X-125291), a pharmacopoeial impurity reference standard (molecular formula C5H10ClNOHCl, MW 172.05 g/mol) used for the identification and quantification of trace impurities in APIs.

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 91 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.
