Chemical Structure

Deoxycholic acid Impurity 21 CAS 73410-01-2 chemical structure

Description

Deoxycholic acid Impurity 21 (C25H40O3) contains a steroid 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).

Deoxycholic acid Impurity 21 (CAS 73410-01-2) is a certified pharmaceutical impurity reference standard with the molecular formula C25H40O3 and a molecular weight of 388.59 g/mol.

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 Deoxycholic acid Impurity 21 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.
