Chemical Structure
Description
4-Fluoro-2-nitrobenzenesulfonyl chloride (CAS 568586-10-7), molecular formula C6H3ClFNO4S and molecular weight 239.61 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system, 4-Fluoro-2-nitrobenzenesulfonyl chloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 239.61 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
