| Hazard Information | Back Directory | [Chemical Properties]
Liquid. Insoluble in water. | [Uses]
Raw material for chemical synthesis. | [Hazard]
Central nervous system impairment,
asthma and hematologic effects. | [Definition]
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. | [Health Hazard]
Trimethyl benzene is an eye,
nose, and respiratory irritant; at high concentrations it causes central nervous system
depression. | [Toxics Screening Level]
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. |

III | [Safety Profile]
Mildly toxic by
ingestion. A skin and eye irritant. Flammable
when exposed to heat, flame, and oxidizers.
When heated to decomposition it emits
acrid smoke and irritating fumes. See also
