Sarpogrelate Impurity 11 CAS 138656-66-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Sarpogrelate Impurity 11.

CATO supplies Sarpogrelate Impurity 11 (CAS 138656-66-3), a pharmacopoeial impurity reference standard (molecular formula C19H25NO3, MW 315.41 g/mol) used for the identification and quantification of trace impurities in APIs.

Sarpogrelate Impurity 11 (C19H25NO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

CATO manufactures Sarpogrelate Impurity 11 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.
