Cholic Acid Impurity 26 CAS CATO-C4X-116026 chemical structure

Description

CATO manufactures Cholic Acid Impurity 26 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.

CATO supplies Cholic Acid Impurity 26 (CAS CATO-C4X-116026), a pharmacopoeial impurity reference standard (molecular formula C19H30O2, MW 290.44 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Cholic Acid Impurity 26 (C19H30O2) is characterized by a steroid core, a hydroxyl group, an ether linkage. 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.
