Cholic Acid Impurity N2 CAS 2958-05-6 chemical structure

Description

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 supplies Cholic Acid Impurity N2 (CAS 2958-05-6), a pharmacopoeial impurity reference standard (molecular formula C24H36O4, MW 388.54 g/mol) used for the identification and quantification of trace impurities in APIs.

Cholic Acid Impurity N2 (C24H36O4) contains a flavonoid core, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), Cholic Acid Impurity N2 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
