Muricholic Acid Impurity 22 CAS 111824-32-9

Description

The occurrence of Muricholic Acid Impurity 22 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.

Muricholic Acid Impurity 22 (CAS 111824-32-9) is a certified pharmaceutical impurity reference standard with the molecular formula C27H44O6 and a molecular weight of 464.63 g/mol.

Owing to a steroid core, a hydroxyl group, an ether linkage, Muricholic Acid Impurity 22 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 464.63 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).

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.

As a certified reference material (CRM), Muricholic Acid Impurity 22 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
