Chemical Structure
Description
Owing to a steroid core, a hydroxyl group, an ether linkage, Ursodeoxycholic Acid Impurity 127 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 390.56 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO supplies Ursodeoxycholic Acid Impurity 127 (CAS CATO-C4X-1422127), a pharmacopoeial impurity reference standard (molecular formula C24H38O4, MW 390.56 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 Ursodeoxycholic Acid Impurity 127 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.
