Chemical Structure

Chenodeoxycholic Acid Impurity 5 CAS 59132-31-9 chemical structure

Description

The occurrence of Chenodeoxycholic Acid Impurity 5 is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

As a process- or degradation-related impurity, Chenodeoxycholic Acid Impurity 5 (CAS 59132-31-9, C24H40O7S) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Structurally, Chenodeoxycholic Acid Impurity 5 (C24H40O7S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 472.64 g/mol, it falls into the moderately-high-molecular-weight range. 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).

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 Chenodeoxycholic Acid Impurity 5 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.
