  • Applications

    2,4-Diaminotoluene is primarily used as an intermediate in the production of toluene diisocyanates (TDI), which serve as key precursors for polyurethanes used in polyurethane foams for insulation and interiors, coatings, elastomers, and adhesives. It is also employed as a chemical intermediate in dye and pigment chemistry, contributing to certain aromatic dye formulations. Additionally, it is evaluated as a building block for specialty polymers and crosslinking systems in industrial formulations, with usage subject to local regulations and formulation limits.
