1,3-Dichlorobenzene (also known as ''meta''-dichlorobenzene) is an
aryl chloride
In organic chemistry, an aryl halide (also known as a haloarene) is an aromatic compound in which one or more hydrogen atoms directly bonded to an aromatic ring are replaced by a halide ion (such as fluorine F''−'', chlorine Cl−1,−3,−5, bro ...
and isomer of
dichlorobenzene There are three distinct chemical compounds which are dichlorobenzenes:
* 1,2-Dichlorobenzene or ''ortho''-dichlorobenzene;
* 1,3-Dichlorobenzene or ''meta''-dichlorobenzene;
* 1,4-Dichlorobenzene or ''para''-dichlorobenzene.
All three isomers are ...

2. It is the least common of the three isomers of dichlorobenzene, and it is a colorless liquid that is insoluble in water. It is produced as a minor byproduct of the
chlorination of
benzene
Benzene is an Organic compound, organic chemical compound with the Chemical formula#Molecular formula, molecular formula C6H6. The benzene molecule is composed of six carbon atoms joined in a planar hexagonal Ring (chemistry), ring with one hyd ...
, but can also be prepared in a directed manner by the
Sandmeyer reaction of
3-chloroaniline. It also arises from the isomerization of the other dichlorobenzenes at high temperature.
