Chemical Structure

5α-PREGNAN-3α, 17, 20β-TRIOL CAS 13933-75-0 chemical structure

Description

5α-PREGNAN-3α, 17, 20β-TRIOL (CAS 13933-75-0), molecular formula C21H36O3 and molecular weight 336.51 g/mol, is a CATO reference standard with documented purity and traceability.

5α-PREGNAN-3α, 17, 20β-TRIOL (C21H36O3) 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.

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

CATO manufactures 5α-PREGNAN-3α, 17, 20β-TRIOL under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
