Chemical Structure

7a,12a-Dihydroxy-5b-cholestan-3-one CAS 547-97-7 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.

7a,12a-Dihydroxy-5b-cholestan-3-one (CAS 547-97-7), molecular formula C27H46O3 and molecular weight 418.65 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 7a,12a-Dihydroxy-5b-cholestan-3-one (C27H46O3) 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).

CATO manufactures 7a,12a-Dihydroxy-5b-cholestan-3-one 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.
