Chemical Structure

6-chloro-N-(3,4-difluorophenyl)pyridine-3-sulfonamide CAS 1002244-75-8 chemical structure

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 6-chloro-N-(3,4-difluorophenyl)pyridine-3-sulfonamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 304.70 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

6-chloro-N-(3,4-difluorophenyl)pyridine-3-sulfonamide (CAS 1002244-75-8), molecular formula C11H7ClF2N2O2S and molecular weight 304.70 g/mol, is a CATO reference standard with documented purity and traceability.
