Chemical Structure
Description
The occurrence of (2,6-DIBROMOPHENYL)METHANESULFONYL CHLORIDE is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(2,6-DIBROMOPHENYL)METHANESULFONYL CHLORIDE (CAS 256651-55-5) is a high-purity analytical reference standard with the molecular formula C7H5Br2ClO2S and a molecular weight of 348.44 g/mol.
(2,6-DIBROMOPHENYL)METHANESULFONYL CHLORIDE (C7H5Br2ClO2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 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.
