4-Chloro-3-nitrobenzenesulfonyl fluoride CAS 349-04-2

Description

The occurrence of 4-Chloro-3-nitrobenzenesulfonyl fluoride is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Chloro-3-nitrobenzenesulfonyl fluoride (CAS 349-04-2), molecular formula C6H3ClFNO4S and molecular weight 239.61 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-Chloro-3-nitrobenzenesulfonyl fluoride (C6H3ClFNO4S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. 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).
