1,3-Diisopropylbenzene is an aromatic hydrocarbon with the formula C6H4(CHMe2)2 (Me = CH3).

It is one of three isomeric diisopropylbenzenes.

This colorless liquid is prepared by thermal isomerization of 1,4-diisopropylbenzene over a solid acid catalyst.

[1] It is the principal industrial precursor to resorcinol via the Hock rearrangement.
