Chemical Structure
Description
Based on its molecular formula C7H3BrClF3O3S, 3-Bromo-4-(trifluoromethoxy)benzenesulfonyl chloride contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 339.51 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
3-Bromo-4-(trifluoromethoxy)benzenesulfonyl chloride (CAS 883146-06-3) is a high-purity analytical reference standard with the molecular formula C7H3BrClF3O3S and a molecular weight of 339.51 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
