What is Bromobenzene?

Plain description, key identifiers and synonyms

Bromobenzene is the simplest member of the class of bromobenzenes, that is benzene in which a single hydrogen has been substituted by a bromine. A liquid at room temperature (m.p. 30C, b.p.760 156C), it is used as a solvent, particularly for large-scale crystallisations, and for the introduction of phenyl groups in organic synthesis. It has a role as a non-polar solvent, a hepatotoxic agent and a mouse metabolite. It is a volatile organic compound, a bromoarene and a member of bromobenzenes.
