1,3-Benzenediamine Specification

1,3-Benzenediamine, its cas register number is 108-45-2. It also can be call 1,3-Phenylenediamine; 3-Aminoaniline;
Benzene, 1,3-diamino-; Metaphenylenediamine; m-Aminoaniline; m-Benzenediamine; m-Diaminobenzene; m-Fenylendiamin; m-Phenylenediamine. 1,3-diaminobenzene, is an organic compound with the formula C₆H₄(NH₂)₂. It is an isomer of o-phenylenediamine and p-phenylenediamine. It is a colourless solid. m-Phenylenediamine is produced by hydrogenation of 1,3-dinitrobenzene. The dinitrobenzene is prepared by dinitration of benzene.
