Chemical Structure
Description
CATO supplies 4-(Bis((4-chlorophenyl)thio)methylene)-2-phenyloxazol-5(4H)-one (CAS 67002-19-1), a certified reference material (molecular formula C22H13Cl2NO2S2, MW 458.38 g/mol) for analytical method development and quality control.
The molecular framework of 4-(Bis((4-chlorophenyl)thio)methylene)-2-phenyloxazol-5(4H)-one (C22H13Cl2NO2S2) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 4-(Bis((4-chlorophenyl)thio)methylene)-2-phenyloxazol-5(4H)-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.
