p-Nitroaniline is an important chemical raw material, which is widely used in dye, medicine, pesticide and other fields. The following are the upstream and downstream related products of p-nitroaniline:

upstream products:

1. Aniline: Aniline is the main raw material of p-nitroaniline, and p-nitroaniline can be produced through nitration reaction.

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

downstream products:

1. p-aminophenol: p-nitroaniline can be prepared by reduction reaction p-aminophenol, which is an important dye intermediate.

2. p-nitrophenol: p-nitroaniline can be prepared by hydrolysis reaction of p-nitrophenol, which is also an important chemical raw material, can be used for the preparation of medicine, pesticides and so on.

3. Azo dyes: p-nitroaniline can be coupled with other aromatic compounds to generate a variety of azo dyes, which are widely used in textile, leather and other industries.

4. pesticides: derivatives of nitroaniline can be used as pesticides, with bactericidal, insecticidal and other effects.

In short, as an important chemical raw material, p-nitroaniline has a wide range of upstream and downstream related products, involving dyes, pharmaceuticals, pesticides and other fields.
