Chemical Structure
Description
Owing to bromine substitution, a polycyclic aromatic system, 2-Bromo-11,11-dimethyl-11H-benzo[b]fluorene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 323.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
