Finasteride Impurity 47 CAS CATO-C4X-164547

Description

The occurrence of Finasteride Impurity 47 is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Finasteride Impurity 47 (CAS CATO-C4X-164547) is a certified pharmaceutical impurity reference standard with the molecular formula C15H26O2 and a molecular weight of 238.37 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Finasteride Impurity 47 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 238.37 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), Finasteride Impurity 47 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.
