4-(Benzofuran-2-carbonyl)-5-(4-chlorophenyl)-3-hydroxy-1-(thiazol-2-yl)-1,5-dihydro-2H-pyrrol-2-one (CAS 618369-75-8), molecular formula C22H13ClN2O4S and molecular weight 436.87 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(Benzofuran-2-carbonyl)-5-(4-chlorophenyl)-3-hydroxy-1-(thiazol-2-yl)-1,5-dihydro-2H-pyrrol-2-one (C22H13ClN2O4S) is characterized by a flavonoid 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 the protonation state of its nitrogen-containing groups, 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.
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.
