Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 229.07 g/mol gives 2-bromo-3,5-dimethylbenzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-bromo-3,5-dimethylbenzoic acid (CAS 7697-33-8) is a high-purity analytical reference standard with the molecular formula C9H9BrO2 and a molecular weight of 229.07 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 2-bromo-3,5-dimethylbenzoic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 229.07 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
