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.
(3alpha,5alpha,6beta,17beta)-2-(Hydroxymethyl)-17-methylandrostane-3,6,17-triol (CAS 118139-60-9) is a high-purity analytical reference standard with the molecular formula C21H36O4 and a molecular weight of 352.51 g/mol.
The molecular framework of (3alpha,5alpha,6beta,17beta)-2-(Hydroxymethyl)-17-methylandrostane-3,6,17-triol (C21H36O4) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures (3alpha,5alpha,6beta,17beta)-2-(Hydroxymethyl)-17-methylandrostane-3,6,17-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.
