2,4-Dinitrotoluene

2,4-Dinitrotoluene, commonly abbreviated as 2,4-DNT and also known as 1-methyl-2,4-dinitrobenzene or NSC 7194, is an aromatic nitro compound produced by the controlled nitration of toluene. It is a key intermediate in organic synthesis, particularly within the production of polyurethane precursors and energetic materials.

In polyurethane manufacturing, 2,4-DNT serves as a direct precursor to toluene diamine, which is subsequently converted to toluene diisocyanate, the backbone of flexible foam systems used in automotive seating and aerospace interior components. Its nitro groups drive selective reduction chemistry, enabling controlled downstream synthesis pathways.

2,4-DNT is subject to REACH regulation and requires handling under strict occupational exposure controls due to its classification as a toxic and suspected carcinogenic substance. Procurement professionals should confirm supplier compliance documentation, including safety data sheets aligned with EU GHS standards. Packaging and available grades vary by supplier and intended application.
