1,2-Dibromobenzene (o-dibromobenzene) is an aryl bromide and isomer of dibromobenzene. It is one of three isomers, the others being 1,3- and 1,4-dibromobenzene. It is a colorless liquid, although impure samples appear yellowish. The compound is a precursor to many 1,2-disubstituted derivatives of benzene.

Bromobenzene is prepared by the action of bromine on benzene in the presence of Lewis acid catalysts such as aluminium chloride or ferric bromide. [3]Bromobenzene is used to introduce a phenyl group into other compounds.
1,3-Dibromobenzene has been used as a starting material in the synthesis of antiviral Lufotrelvir, in human clinical trials for the treatment of COVID-19. [3] The first step is formylation of 1,3-dibromobenzene to 2,6-dibromobenzaldehyde, by lithiation with lithium diisopropylamide in THF , followed by quenching with dimethylformamide .
Owing to its symmetrical structure and reactivity, 1,2,4,5-tetrabromobenzene is a precursor to nematic liquid crystals [6] with crossed mesogens and for columnar (discotic) liquid crystals [7] [8] with an extensive planar, "board-like" tetrabenzoanthracene core.
