2,4-Diaminotoluene is a poisonous chemical compound which, in its pure form, consists of brownish scales with a weak smell of ammonia . It is an intermediate product in the production of polyurethane and is produced in the catalytic hydrogenation of 2,4-dinitrotoluene . 2,4-diaminotoluene is carcinogenic.
use
By far the largest amount of 2,4-diaminotoluene is produced as an intermediate product in the production of isocyanates , which are the basis for polyurethane plastics . Smaller amounts are used for the synthesis of industrial dyes.
safety instructions
2,4-Diaminotoluene is considered to be carcinogenic, is possibly teratogenic and possibly mutagenic.
