Chemical Structure
Description
The occurrence of 1,2-Dibromo-4-(trifluoromethyl)benzene is closely related to fluorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1,2-Dibromo-4-(trifluoromethyl)benzene (CAS 7657-08-1), molecular formula C7H3Br2F3 and molecular weight 303.90 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C7H3Br2F3, 1,2-Dibromo-4-(trifluoromethyl)benzene contains fluorine/bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 303.90 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
