Bromobenzenes

Bromobenzene is an aryl bromide and the simplest of the bromobenzenes, consisting of a benzene ring substituted with one bromine atom. Its chemical formula is . It is a colourless liquid although older samples can appear yellow. It is a reagent in organic synthesis.

1,4-Dibromobenzene (p-dibromobenzene) is an aryl bromide and isomer of dibromobenzene that is solid at room temperature. It has a strong smell similar to that of the lighter chlorine analogue. It can be used as a precursor to the dye 6,6-dibromoindigo.

Hexabromobenzene (HBB) is an organobromine compound with the formula . It features a central benzene ring with six bromine substituents. Hexabromobenzene is a white powder that is not soluble in water but is soluble in ethanol, ether, and benzene. Its bromine content by weight is above 86%.

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. For example, it is a precursor to 1,2-dicyanobenzene and dithioethers.

Tribromobenzenes are a group of bromobenzenes with the formula C6H3Br3, consisting of three bromine atoms bonded to a central benzene ring.
