Toluene 2,4-diisocyanate is a toluene meta-diisocyanate in which the isocyanato groups are at positions 2 and 4 relative to the methyl group on the benzene ring. It has a role as an allergen and a hapten. Toluene-2,4-diisocyanate appears as colorless to yellow or dark liquid or solid with a sweet, fruity, pungent odor. Melting point 68 °F (20 °C). Evolves CO2 when moist.
