Chemical Structure

Ursodeoxycholic Acid impurity 101 CAS CATO-C4X-1422101 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 499.70 g/mol gives Ursodeoxycholic Acid impurity 101 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Ursodeoxycholic Acid impurity 101 (CAS CATO-C4X-1422101, C26H45NO6S) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Ursodeoxycholic Acid impurity 101 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 499.70 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), Ursodeoxycholic Acid impurity 101 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.
