The occurrence of 2,2',5,5'-Tetrabromodiphenyl ether is closely related to a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2,2',5,5'-Tetrabromodiphenyl ether (CAS 446254-24-6), a certified reference material (molecular formula C12H6Br4O, MW 485.79 g/mol) for analytical method development and quality control.
Owing to a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 2,2',5,5'-Tetrabromodiphenyl ether is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 485.79 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
