2,4-Diaminotoluene is used primarily as an intermediate in the production of toluene diisocyanate, which is used to produce polyurethane.
The primary use of 2,4-Diaminotoluene has been as an intermediate in the production of 2,4-toluene diisocyanate, which in turn is used to produce polyurethane (HSDB 2009).
2,4-Diaminotoluene has beenused in the production of about 60 dyes, 28 of which are believed to have been produced in significant amounts in the mid 1970s.
These dyes generally have been used to color silk, wool, paper, furs, and leather.
Some have also been used to dye cotton fibers and other cellulosic fibers, in spirit varnishes and wood stains, as indicators in the manufacture of pigments, and as biological stains.
2,4-Diaminotoluene has been used as a developer for direct dyes, particularly to obtain black, dark blue, and brown shades, and to obtain navy blue and black colors on leather.
2,4-Diaminotoluene was also used in hair-dye formulations until this use ceased in the United States in 1971 (IARC 1978).
