Chemical Structure

5α-ANDROSTAN-3β, 11β, 17β-TRIOL CAS 32212-65-0 chemical structure

Description

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.

CATO supplies 5α-ANDROSTAN-3β, 11β, 17β-TRIOL (CAS 32212-65-0), a certified reference material (molecular formula C19H32O3, MW 308.46 g/mol) for analytical method development and quality control.

The molecular framework of 5α-ANDROSTAN-3β, 11β, 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 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.
