Chemical Structure

Cholic Acid Impurity 60 CAS 1632118-78-5 chemical structure

Description

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.

Cholic Acid Impurity 60 (CAS 1632118-78-5) is a certified pharmaceutical impurity reference standard with the molecular formula C32H46O6S and a molecular weight of 558.77 g/mol.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, Cholic Acid Impurity 60 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 558.77 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).

CATO manufactures Cholic Acid Impurity 60 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.
