2,4-Diaminotoluene Chemical Properties,Uses,Production

Chemical Properties

brown crystalline powder, crystals or flakes


Aromatic amines likely to have high carcinogenic potency. QSARs of aromatic amines.


ChEBI: An aminotoluene that is para-toluidine with an additional amino group at position 2.

General Description

A colorless crystalline solid. Toxic by ingestion and inhalation. Irritates skin and eyes. Slightly soluble in water and neutrally buoyant in water. Decomposes with emission of toxic oxides of nitrogen at high temperatures. Used in making dyes.

Air & Water Reactions

Soluble in water, alcohol and ether.

Reactivity Profile

2,4-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. May generate hydrogen, a flammable gas, in combination with strong reducing agents such as hydrides. Reacts vigorously with oxidizing agents [USCG, 1999].


A possible carcinogen.

Purification Methods

Recrystallise the diamine from water containing a very small amount of sodium dithionite (to prevent air oxidation), and dry it under vacuum. It also crystallises from *benzene. [Beilstein 13 IV 235.]
