Chemical Structure

Clascoterone Impurity 12 CAS 2693-85-8 chemical structure

Description

Owing to a flavonoid core, a hydroxyl group, an ether linkage, Clascoterone Impurity 12 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 386.52 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 supplies Clascoterone Impurity 12 (CAS 2693-85-8), a pharmacopoeial impurity reference standard (molecular formula C24H34O4, MW 386.52 g/mol) used for the identification and quantification of trace impurities in APIs.

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), Clascoterone Impurity 12 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.
