Abiraterone Impurity N8 CAS 2487-48-1 chemical structure

Description

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.

Abiraterone Impurity N8 (CAS 2487-48-1) is a certified pharmaceutical impurity reference standard with the molecular formula C19H28O3 and a molecular weight of 304.42 g/mol.

Owing to a steroid core, a hydroxyl group, an ether linkage, Abiraterone Impurity N8 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 304.42 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).

As a certified reference material (CRM), Abiraterone Impurity N8 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.
