Chemical Structure

5, 16-ANDROSTADIEN-3β-OL CAS 1224-94-8 chemical structure

Description

As a certified reference material (CRM), 5, 16-ANDROSTADIEN-3β-OL 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.

As a process- or degradation-related impurity, 5, 16-ANDROSTADIEN-3β-OL (CAS 1224-94-8, C19H28O) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to a steroid core, a hydroxyl group, an ether linkage, 5, 16-ANDROSTADIEN-3β-OL is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 272.43 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.
