Chemical Structure

Olmesartan Impurity 93 CAS CATO-C4X-109793 chemical structure

Description

The molecular framework of Olmesartan Impurity 93 (C7H6O7) is characterized by a carbohydrate-derived structure. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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).

CATO supplies Olmesartan Impurity 93 (CAS CATO-C4X-109793), a pharmacopoeial impurity reference standard (molecular formula C7H6O7, MW 202.12 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.

CATO manufactures Olmesartan Impurity 93 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.
