Chemical Structure
Description
CATO supplies 3-(4-Chlorophenyl)-3-[(4-fluorophenyl)sulfanyl]-1-(4-methoxyphenyl)propan-1-one (CAS 303091-31-8), a certified reference material (molecular formula C22H18ClFO2S, MW 400.89 g/mol) for analytical method development and quality control.
Owing to a steroid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 3-(4-Chlorophenyl)-3-[(4-fluorophenyl)sulfanyl]-1-(4-methoxyphenyl)propan-1-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 400.89 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 3-(4-Chlorophenyl)-3-[(4-fluorophenyl)sulfanyl]-1-(4-methoxyphenyl)propan-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.
