Chemical Structure

5α-ANDROSTAN-3α-OL CAS 7657-50-3 chemical structure

Description

CATO manufactures 5α-ANDROSTAN-3α-OL 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.

5α-ANDROSTAN-3α-OL (CAS 7657-50-3), molecular formula C19H32O and molecular weight 276.46 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 5α-ANDROSTAN-3α-OL (C19H32O) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 276.46 g/mol, it falls into the medium-molecular-weight range. 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.
