Chemical Structure
Description
The occurrence of 2-Bromo-9,9-dimethyl-5-phenyl-9H-fluorene is closely related to bromine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Bromo-9,9-dimethyl-5-phenyl-9H-fluorene (CAS 2222970-00-3) is a high-purity analytical reference standard with the molecular formula C21H17Br and a molecular weight of 349.26 g/mol.
Owing to bromine substitution, a polycyclic aromatic system, 2-Bromo-9,9-dimethyl-5-phenyl-9H-fluorene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 349.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
