trimethylbenzene Usage And Synthesis

Chemical Properties

Liquid. Insoluble in water.

Uses

Raw material for chemical synthesis.

Uses

As a raw material in chemical syntheses; as ultraviolet stabilizers in plastics; found in solvents and as a constituent of gasoline.

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.

Hazard

Central nervous system impairment, asthma and hematologic effects.

Health Hazard

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

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 individual trimethyl benzene isomers.
