Testosterone Impurity 62 CAS 6173-23-5 chemical structure

Description

CATO supplies Testosterone Impurity 62 (CAS 6173-23-5), a pharmacopoeial impurity reference standard (molecular formula C19H30O, MW 274.44 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a steroid core, a hydroxyl group, an ether linkage, Testosterone Impurity 62 is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 274.44 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).

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), Testosterone Impurity 62 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.
