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.
CATO supplies 1-(4-Hydroxy-3,5-dimethylphenyl)-2-(p-tolylsulfinyl)ethan-1-one (CAS 344279-92-1), a certified reference material (molecular formula C17H18O3S, MW 302.39 g/mol) for analytical method development and quality control.
The molecular framework of 1-(4-Hydroxy-3,5-dimethylphenyl)-2-(p-tolylsulfinyl)ethan-1-one (C17H18O3S) is characterized by a steroid core, a sulfone group, 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures 1-(4-Hydroxy-3,5-dimethylphenyl)-2-(p-tolylsulfinyl)ethan-1-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.
