Chemical Structure
Description
Based on its molecular formula C12H8BrCl, 4'-Bromo-3-chloro-1,1'-biphenyl contains chlorine/bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 267.55 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 4'-Bromo-3-chloro-1,1'-biphenyl (CAS 91354-09-5), a certified reference material (molecular formula C12H8BrCl, MW 267.55 g/mol) for analytical method development and quality control.
