Chemical Structure
Description
The molecular framework of 4-PREGNEN-11β, 21-DIOL-3, 20-DIONE 21-SULPHATE, SODIUM SALT (C21H29O7SNa) is characterized by a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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).
