Chemical Structure
Description
The occurrence of 5 β-Cholestane-3 β,5,6 β-triol is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5 β-Cholestane-3 β,5,6 β-triol (CAS 79254-30-1) is a high-purity analytical reference standard with the molecular formula C27H48O3 and a molecular weight of 420.67 g/mol.
The molecular framework of 5 β-Cholestane-3 β,5,6 β-triol (C27H48O3) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
