7α-Hydroxy Cholesterol CAS 566-26-7 chemical structure

Description

CATO supplies 7α-Hydroxy Cholesterol (CAS 566-26-7), a certified reference material (molecular formula C27H46O2, MW 402.65 g/mol) for analytical method development and quality control.

The molecular framework of 7α-Hydroxy Cholesterol (C27H46O2) 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 7α-Hydroxy Cholesterol 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.
