Chemical Structure
Description
The occurrence of Ursodeoxycholic Acid impurity 95 is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Ursodeoxycholic Acid impurity 95 (CAS CATO-C4X-142295) is a certified pharmaceutical impurity reference standard with the molecular formula C24H38O4 and a molecular weight of 390.56 g/mol.
Owing to a steroid core, a hydroxyl group, an ether linkage, Ursodeoxycholic Acid impurity 95 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 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.
CATO manufactures Ursodeoxycholic Acid impurity 95 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.
