Chemical Structure
Description
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 4-Methyl-3-nitrobenzenesulfonyl fluoride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 219.19 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).
4-Methyl-3-nitrobenzenesulfonyl fluoride (CAS 1535-47-3), molecular formula C7H6FNO4S and molecular weight 219.19 g/mol, is a CATO reference standard with documented purity and traceability.
