3,4-Diaminotoluene Chemical Properties,Usage,Production

Chemical Properties

Off-white small blocks

Uses

5-Methylbenzotriazole intermediate.

Uses

4-Methyl-o-phenylenediamine was employed as chromogenic reagent in the spectrophotometric determination of selenium(IV). It was used in the synthesis of an asymmetrical tetradentate Schiff base via condensation with dehydroacetic acid and salicylic aldehyde.

Synthesis Reference(s)

Tetrahedron Letters, 42, p. 2277, 2001 DOI: 10.1016/S0040-4039(01)00163-0

General Description

A colorless to brownish purple crystalline solid. Toxic by ingestion and inhalation and an irritant to skin and eyes. Soluble in water, alcohol and ether. Decomposes to emit toxic oxides of nitrogen when heated to high temperature. Used in making dyes.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

3,4-Diaminotoluene 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.

Fire Hazard

Flash point data for 3,4-Diaminotoluene are not available. 3,4-Diaminotoluene is probably combustible.
