Chemical Structure
Description
CATO supplies CHOLESTAN-5α-OL-3, 6-DIONE (CAS 20281-70-3), a certified reference material (molecular formula C27H44O3, MW 416.64 g/mol) for analytical method development and quality control.
The molecular framework of CHOLESTAN-5α-OL-3, 6-DIONE (C27H44O3) 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.
CATO manufactures CHOLESTAN-5α-OL-3, 6-DIONE 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.
