Description
2-FLUOROBENZENE-1-SULFONYL CHLORIDE 2-FLUOROBENZENESULPHONYL CHLORIDE 2-Fluorobenzenesulfonyl chloride 2905-21-7 AS03383 BENZENESULFONYL CHLORIDE, 2-FLUORO- BUTTPARK 27\04-29 O-FLUOROBENZENESULFONYL CHLORIDE (C6H10ClFO2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
2-FLUOROBENZENE-1-SULFONYL CHLORIDE 2-FLUOROBENZENESULPHONYL CHLORIDE 2-Fluorobenzenesulfonyl chloride 2905-21-7 AS03383 BENZENESULFONYL CHLORIDE, 2-FLUORO- BUTTPARK 27\04-29 O-FLUOROBENZENESULFONYL CHLORIDE (CAS 2905-21-7), molecular formula C6H10ClFO2S and molecular weight 200.66 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
