Cycloserine Impurity 7 CAS CATO-C4X-22647 chemical structure

Description

CATO supplies Cycloserine Impurity 7 (CAS CATO-C4X-22647), a pharmacopoeial impurity reference standard (molecular formula C10H14O3S, MW 214.28 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Cycloserine Impurity 7 (C10H14O3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 Cycloserine Impurity 7 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.
