Chemical Structure

5-ANDROSTEN-3β, 16β, 17β-TRIOL CAS 14474-06-7 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.

5-ANDROSTEN-3β, 16β, 17β-TRIOL (CAS 14474-06-7), molecular formula C19H30O3 and molecular weight 306.44 g/mol, is a CATO reference standard with documented purity and traceability.

5-ANDROSTEN-3β, 16β, 17β-TRIOL (C19H30O3) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
