The occurrence of 2-Bromo-4-methylphenyl trifluoromethanesulphonate is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Bromo-4-methylphenyl trifluoromethanesulphonate (CAS 138719-95-6) is a high-purity analytical reference standard with the molecular formula C8H6BrF3O3S and a molecular weight of 319.10 g/mol.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system, 2-Bromo-4-methylphenyl trifluoromethanesulphonate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 319.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
