Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 352.40 g/mol gives 2,5-Dibromo-3-fluorobenzenesulfonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2,5-Dibromo-3-fluorobenzenesulfonyl chloride (CAS 1804416-65-6) is a high-purity analytical reference standard with the molecular formula C6H2Br2ClFO2S and a molecular weight of 352.40 g/mol.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution, an aromatic ring system, 2,5-Dibromo-3-fluorobenzenesulfonyl chloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 352.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
