Chemical Structure
Description
The molecular framework of 4-Methoxy-3-{[4-(pyridin-2-yl)piperazin-1-yl]sulfonyl}benzoic acid (C17H19N3O5S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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).
4-Methoxy-3-{[4-(pyridin-2-yl)piperazin-1-yl]sulfonyl}benzoic acid (CAS 748776-35-4) is a high-purity analytical reference standard with the molecular formula C17H19N3O5S and a molecular weight of 377.41 g/mol.
