Description
CATO manufactures Deoxycholic acid Impurity 2 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.
As a process- or degradation-related impurity, Deoxycholic acid Impurity 2 (CAS CATO-C4X-33592, C24H38O3) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Owing to a steroid core, a hydroxyl group, an ether linkage, Deoxycholic acid Impurity 2 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 374.56 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
