Chemical Structure
Description
Structurally, 2-(4-Bromophenyl)naphthalene (C16H11Br) contains bromine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 283.16 g/mol, it falls into the medium-molecular-weight range. 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).
