Chemical Structure
Description
The molecular framework of 4-(3-Chlorophenyl)-5-(ethylsulfonyl)-2-thioxo-1,2-dihydropyridine-3-carbonitrile (C14H11ClN2O2S2) is characterized by a nitrogen-containing heterocyclic scaffold, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
4-(3-Chlorophenyl)-5-(ethylsulfonyl)-2-thioxo-1,2-dihydropyridine-3-carbonitrile (CAS 1707567-09-6), molecular formula C14H11ClN2O2S2 and molecular weight 338.83 g/mol, is a CATO reference standard with documented purity and traceability.
