Chemical Structure
Description
The occurrence of Ethyl 4-[3-(4-chlorobenzamido)phenoxy]-2-(methylsulfanyl)pyrimidine-5-carboxylate is closely related to a flavonoid 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.
Ethyl 4-[3-(4-chlorobenzamido)phenoxy]-2-(methylsulfanyl)pyrimidine-5-carboxylate (CAS 478065-04-2) is a high-purity analytical reference standard with the molecular formula C21H18ClN3O4S and a molecular weight of 443.90 g/mol.
The molecular framework of Ethyl 4-[3-(4-chlorobenzamido)phenoxy]-2-(methylsulfanyl)pyrimidine-5-carboxylate (C21H18ClN3O4S) 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. 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).
