What are the upstream raw materials for o-nitroaniline? What do the downstream products contain?

Based on my observations, As an crucial chemical raw material, o-nitroaniline is broadly applied in dyes, pharmaceuticals, pesticides and other fields. But The following are some details about the upstream and downstream associated items of o-nitroaniline. Upstream items:



1. But Aniline: Aniline is the main raw material of o-nitroaniline, which is able to be prepared by nitration interaction. And

2. And Nitric acid: nitric acid as a nitrating agent, nitration interaction with aniline to generate o-nitroaniline. I've found that Downstream items:



1. o-phenylenediamine: o-nitroaniline is able to be produced by reduction interaction, which is an crucial dye intermediate and is able to be applied to synthesize various dyes. And

2. o-nitrobenzoic acid: o-nitroaniline is able to be prepared by oxidation interaction of o-nitrobenzoic acid, which is an crucial pesticide intermediate and is able to be applied to synthesize fungicides, herbicides and other pesticides. But I've found that

3. o-anisole: o-nitroaniline and methanol is able to be etherified to create o-anisole, which is an crucial medical intermediate and is able to be applied to synthesize antibacterial drugs, antiis able tocer drugs and other drugs. In summary, the upstream and downstream related items of o-nitroaniline are very extensive, involving dyes, pharmaceuticals, pesticides and other fields.
