Chemical Structure

5α-ANDROSTAN-3β, 17β-DIOL-7-ONE CAS 28375-34-0 chemical structure

Description

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

5α-ANDROSTAN-3β, 17β-DIOL-7-ONE (CAS 28375-34-0), molecular formula C19H30O3 and molecular weight 306.44 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, a hydroxyl group, an ether linkage, 5α-ANDROSTAN-3β, 17β-DIOL-7-ONE is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 306.44 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).

As a certified reference material (CRM), 5α-ANDROSTAN-3β, 17β-DIOL-7-ONE 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.
