Chemical Structure
Description
4,6-Dibromo-2,3-difluorobenzene-1-sulfonyl chloride (CAS 1806347-25-0) is a high-purity analytical reference standard with the molecular formula C6HBr2ClF2O2S and a molecular weight of 370.39 g/mol.
4,6-Dibromo-2,3-difluorobenzene-1-sulfonyl chloride (C6HBr2ClF2O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution, an aromatic ring system. 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
