Chemical Structure
Description
Based on its molecular formula C11H9Br, 1-Bromo-3-methylnaphthalene contains bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 221.09 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).
1-Bromo-3-methylnaphthalene (CAS 54357-18-5) is a high-purity analytical reference standard with the molecular formula C11H9Br and a molecular weight of 221.09 g/mol.
