o-Nitroaniline is an extremely important intermediate in the dye industry. It can be directly used in the synthesis of varieties: direct sunfast black G, direct green B, BE, 2B-2N, black green NB, direct gray D, acid black 10B, ATT , Disperse red P-4G, cationic dark yellow 2RL, fur black D, p-phenylenediamine, o-chloro-p-nitroaniline, 2.6-dichloro-4-nitroaniline, 5-nitro-2-chlorophenol, etc., It can also be used to synthesize pesticide chlornitramine and medicine californica; at the same time, it is also the raw material of antioxidant, light stabilizer, developer and so on. The disperse dyes synthesized abroad with p-nitroaniline as the diazo component are: C, I disperse orange 1, 3, 7, 21, etc., red 1, 2, 7, 17, etc., blue 259; black 2, 3, 28 , 29 et al.
This product is the ice-dye red GG color base, which can be used as black salt K for dyeing and printing of cotton and linen fabrics. But it is mainly used as an azo dye intermediate, such as for the production of direct dark green B, acid medium brown G, acid black 10B, acid wool ATT, fur black D and direct gray D, etc. It can also be used as an intermediate for pesticides and veterinary drugs. It can also be used in the production of p-phenylenediamine; antioxidants and preservatives.
