Chemical Structure
Description
Based on its molecular formula C9H10Br2, 1,4-Dibromo-2-isopropylbenzene contains bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 277.98 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.
CATO supplies 1,4-Dibromo-2-isopropylbenzene (CAS 58683-74-2), a certified reference material (molecular formula C9H10Br2, MW 277.98 g/mol) for analytical method development and quality control.
