Note : 2,4-DNT is mostly used as chemical intermediate in the production of toluene diisocyanate
(4-methyl-m-phenylenediisocyanate). It is hydrogenated to yield toluenediamine (TDA)
and this diamine is reacted with phosgene to yield toluenediisocyanate (TDI), which is
used to make flexible polyurethane foams. Other, minor uses as an intermediate include
the use in the production of dyes and dyestuffs and rubber chemicals.
