Chemical Structure
Description
The molecular framework of 2-((2,5-Dichloro-N-phenylphenyl)sulfonamido)-N-(2,4-difluorophenyl)acetamide (C20H14Cl2F2N2O3S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/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).
2-((2,5-Dichloro-N-phenylphenyl)sulfonamido)-N-(2,4-difluorophenyl)acetamide (CAS 339103-14-9), molecular formula C20H14Cl2F2N2O3S and molecular weight 471.30 g/mol, is a CATO reference standard with documented purity and traceability.
