5 Alpha-Androstanedione CAS 846-46-8 chemical structure

Description

As a certified reference material (CRM), 5 Alpha-Androstanedione 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.

5 Alpha-Androstanedione (CAS 846-46-8) is a high-purity analytical reference standard with the molecular formula C19H28O2 and a molecular weight of 288.42 g/mol.

Owing to a steroid core, a hydroxyl group, an ether linkage, 5 Alpha-Androstanedione is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 288.42 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
