Chemical Structure

5α-Androst-16-en-3α-ol CAS 1153-51-1 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5α-Androst-16-en-3α-ol.

5α-Androst-16-en-3α-ol (CAS 1153-51-1) is a high-purity analytical reference standard with the molecular formula C19H30O and a molecular weight of 274.44 g/mol.

The molecular framework of 5α-Androst-16-en-3α-ol (C19H30O) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
