As an important chemical raw material, o-nitroaniline is widely used in dyes, pharmaceuticals, pesticides and other fields. The following are some details about the upstream and downstream associated products of o-nitroaniline.

upstream products:

1. Aniline: Aniline is the main raw material of o-nitroaniline, which can be produced by nitration reaction.

2. nitric acid: nitric acid as a nitrating agent, nitration reaction with aniline to generate o-nitroaniline.

downstream products:

1. o-phenylenediamine: o-nitroaniline can be prepared by reduction reaction o-phenylenediamine, which is an important dye intermediate and can be used to synthesize various dyes.

2. o-nitrobenzoic acid: o-nitroaniline can be prepared by oxidation reaction of o-nitrobenzoic acid, which is an important pesticide intermediate and can be used for the synthesis of fungicides, herbicides and other pesticides.

3. o-amino anisole: o-nitroaniline and methanol etherification reaction can produce o-amino anisole, which is an important pharmaceutical intermediates, can be used for the synthesis of antibacterial drugs, anticancer drugs and other drugs.

In summary, the upstream and downstream related products of o-nitroaniline are very extensive, involving dyes, pharmaceuticals, pesticides and other fields.
