2,4-dinitrotoluene

2,4-Dinitrotoluene (CAS 121-14-2), commonly referenced as 2,4-DNT, is a nitroaromatic compound used primarily as a chemical intermediate in the synthesis of toluenediamine and toluene diisocyanate.

It functions as a key precursor in polyurethane production and serves as a stabilizer and burn rate modifier in propellant formulations. In the defense and aerospace sectors, it is incorporated into smokeless powder.

The compound is utilized in solid propellant compositions to regulate combustion characteristics. Automotive applications center on its role in producing TDI-based polyurethane foams used in seating and insulation.

These foams are also essential for interior components. As a monomer building block, it feeds into the hydrogenation pathway that yields toluenediamine, the direct precursor to TDI in large-scale manufacturing.

Specialty polymer formulators also evaluate it as a reactive intermediate where controlled nitro-group chemistry is required. This material is supplied as a pale yellow crystalline solid, typically in technical grade.

Bulk quantities are available for industrial procurement, with packaging options ranging from drum to IBC depending on regional handling regulations. Purity specifications generally align with industrial standards.

These standards are suited for intermediate chemical synthesis rather than consumer-facing applications. The material requires careful handling and storage in accordance with safety protocols for nitroaromatic chemicals.
