Chemical Structure
Description
The occurrence of 3-Bromo-4-methyl-5-(trifluoromethyl)benzenesulfonyl chloride is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Bromo-4-methyl-5-(trifluoromethyl)benzenesulfonyl chloride (CAS 2383371-10-4) is a high-purity analytical reference standard with the molecular formula C8H5BrClF3O2S and a molecular weight of 337.54 g/mol.
3-Bromo-4-methyl-5-(trifluoromethyl)benzenesulfonyl chloride (C8H5BrClF3O2S) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 3-Bromo-4-methyl-5-(trifluoromethyl)benzenesulfonyl chloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
