24diaminotoluene

2,4-Diaminotoluene is an organic compound with the chemical formula C7H10N2. It is a derivative of toluene, where two amino groups (-NH2) are attached to the benzene ring at the 2 and 4 positions. It is also known by the names 2,4-toluenediamine and TDA.

This compound typically appears as a crystalline solid, varying in color from off-white to yellow or brown. It is soluble in organic solvents like ethanol and ether, and sparingly soluble in water. 2,4-Diaminotoluene is an isomer of other diaminotoluene compounds, differing in the positions of the amino groups on the toluene ring.

Industrially, 2,4-diaminotoluene is primarily used as a precursor in the production of toluene diisocyanate (TDI). TDI is a key component in the manufacture of polyurethane foams, which are widely used in furniture, bedding, automotive seating, and insulation. The synthesis of TDI involves the reaction of diaminotoluene with phosgene.

Concerns regarding the health effects of 2,4-diaminotoluene exist. It is classified as a suspected human carcinogen by various regulatory agencies. Exposure can occur through inhalation, skin contact, or ingestion, and it is known to be an irritant. Occupational safety measures are important in industrial settings where it is handled to minimize worker exposure.
