m-Dinitrobenzene (1,3-DBN) is a synthetic compound used in manufacture of explosives. 1,3-DNB has been used as a camphor substitute in nitrocellulose, a compound used in explosives and propellants.1,3-DNB was manufactured during both world wars as a component in the explosive roburite. Commercially, 1,3-DNB has been used extensively as an organic intermediate for m-phenylenediamine, a chemical used in the synthesis of aramid fibers and spandex. 1,3-DNB is an industrial chemical used in organic synthesis and dyes. In medicine, 1,3-DNB was used for colorimetric determination of 17-ketosteroids.
