Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 428.69 g/mol gives 5-CHOLESTEN-24-ETHYL-3-OL-7-ONE distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 5-CHOLESTEN-24-ETHYL-3-OL-7-ONE (CAS 2034-74-4), a certified reference material (molecular formula C29H48O2, MW 428.69 g/mol) for analytical method development and quality control.
The molecular framework of 5-CHOLESTEN-24-ETHYL-3-OL-7-ONE (C29H48O2) 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 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.
CATO manufactures 5-CHOLESTEN-24-ETHYL-3-OL-7-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.
