2,4,5-TRIMETHYLANILINE Usage And Synthesis

Chemical Properties

white to light tan crystalline solid

Uses

Manufacture of dyes, organic synthesis.

Definition

ChEBI: 2,4,5-Trimethylaniline is a substituted aniline.

General Description

White crystals or beige powder.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

2,4,5-TRIMETHYLANILINE neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.

Hazard

Questionable carcinogen.

Health Hazard

ACUTE/CHRONIC HAZARDS: When heated to decomposition 2,4,5-TRIMETHYLANILINE emits toxic fumes of nitrogen oxides.

Fire Hazard

Flash point data for 2,4,5-TRIMETHYLANILINE are not available; however, 2,4,5-TRIMETHYLANILINE is probably combustible.

Safety Profile

Confirmed carcinogen with experimental carcinogenic and tumorigenic data. Moderately toxic by ingestion. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx. Used as a dye, pigment, and printing ink. See also ANILINE DYES.
