Captopril EP Impurity A (Captopril disulfide) CAS 64806-05-9

Description

The occurrence of Captopril EP Impurity A (Captopril disulfide) is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Captopril EP Impurity A (Captopril disulfide) (CAS 64806-05-9), a pharmacopoeial impurity reference standard (molecular formula C18H28N2O6S2, MW 432.55 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C18H28N2O6S2, Captopril EP Impurity A (Captopril disulfide) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 432.55 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

CATO manufactures Captopril EP Impurity A (Captopril disulfide) 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.
