Chemical Structure
Description
The occurrence of 1-Benzyl-3-(5-{[(4-chlorophenyl)methyl]sulfanyl}-1,3,4-oxadiazol-2-yl)-1,2-dihydropyridin-2-one is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-Benzyl-3-(5-{[(4-chlorophenyl)methyl]sulfanyl}-1,3,4-oxadiazol-2-yl)-1,2-dihydropyridin-2-one (CAS 242472-24-8) is a high-purity analytical reference standard with the molecular formula C21H16ClN3O2S and a molecular weight of 409.89 g/mol.
The molecular framework of 1-Benzyl-3-(5-{[(4-chlorophenyl)methyl]sulfanyl}-1,3,4-oxadiazol-2-yl)-1,2-dihydropyridin-2-one (C21H16ClN3O2S) 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 the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
