Chemical Structure
Description
The occurrence of 3-Bromo-5-methylbenzene-1-sulfonyl 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.
3-Bromo-5-methylbenzene-1-sulfonyl chloride (CAS 885520-33-2) is a high-purity analytical reference standard with the molecular formula C7H6BrClO2S and a molecular weight of 269.54 g/mol.
The molecular framework of 3-Bromo-5-methylbenzene-1-sulfonyl chloride (C7H6BrClO2S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
