Chemical Structure
Description
The occurrence of 2,2',6,6'-Tetrabromo-1,1'-biphenyl is closely related to bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2,2',6,6'-Tetrabromo-1,1'-biphenyl (CAS 97038-96-5) is a high-purity analytical reference standard with the molecular formula C12H6Br4 and a molecular weight of 469.79 g/mol.
Owing to bromine substitution, an aromatic ring system, 2,2',6,6'-Tetrabromo-1,1'-biphenyl is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 469.79 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).
