Chemical Structure
Description
Structurally, 2,7-Dibromo-4,5,9,10-tetrahydropyrene (C16H12Br2) contains bromine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 364.07 g/mol, it falls into the moderately-high-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).
