Chemical Structure

5α-ANDROSTAN-3β, 11β-DIOL-17-ONE CAS 514-17-0 chemical structure

Description

As a certified reference material (CRM), 5α-ANDROSTAN-3β, 11β-DIOL-17-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.

5α-ANDROSTAN-3β, 11β-DIOL-17-ONE (CAS 514-17-0) is a high-purity analytical reference standard with the molecular formula C19H30O3 and a molecular weight of 306.44 g/mol.

The molecular framework of 5α-ANDROSTAN-3β, 11β-DIOL-17-ONE (C19H30O3) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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