CATO supplies (5E)-3-Ethyl-5-({4-[(4-fluorophenyl)methoxy]phenyl}methylidene)-2-sulfanylidene-1,3-thiazolidin-4-one (CAS 301193-91-9), a certified reference material (molecular formula C19H16FNO2S2, MW 373.46 g/mol) for analytical method development and quality control.
The molecular framework of (5E)-3-Ethyl-5-({4-[(4-fluorophenyl)methoxy]phenyl}methylidene)-2-sulfanylidene-1,3-thiazolidin-4-one (C19H16FNO2S2) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
