ChEBI: 1,2,3-trimethylbenzene is a trimethylbenzene carrying methyl groups at positions 1, 2 and 3. It has been found in Centaurium erythraea. It has a role as a neurotoxin and a plant metabolite.

Trimethyl benzene is an eye, nose, and respiratory irritant; at high concentrations it causes central nervous system depression.

The acute initial threshold screening level (ITSL) for all trimethylbenzene (TMB) isomers combined is 1200 μg/m3 with 8-hr averaging time. The chronic ITSL for all TMB isomers combined is 185 μg/m3 with annual averaging time.
