Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5α-ANDROSTAN-3β, 16β, 17β-TRIOL.
5α-ANDROSTAN-3β, 16β, 17β-TRIOL (CAS 27261-27-4), molecular formula C19H32O3 and molecular weight 308.46 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5α-ANDROSTAN-3β, 16β, 17β-TRIOL (C19H32O3) 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.
