Description
1,3-Dinitrobenzene (1,3-DNB) is an impurity present in the
manufacture of 2,4,6-trinitrotoluene. Workers in munitions
plants are at risk of exposure. While it does not bioaccumulate, it
persists in the environments (air, water, and soil) with slow rates
of degradation. Metabolism in animals (rabbits) results in
reduction of the nitro functionalities to amine functionalities to
produce 2,4-diaminophenol, m-nitroaniline, m-phenylenediamine,
and 2-amino-4-nitrophenol. Human exposure is generally
dermal contact or inhalation of vapor.

Uses
1,3-Dinitrobenzene (1,3-DNB) is an impurity present in the manufacture of 2,4,6-trinitrotoluene. Dinitrobenzene (as a mixture of 1,2-dinitro- 1,3-dinitro- and 1,4-dinitro-isomers) is used in the manufacture of dyes and explosives, and in organic syntheses.
