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

Ortho-nitrophenol plays an crucial role in the field of raw materials to chemical production, and its upstream and downstream related items are extensive. For instance The following are some of the main upstream and downstream associated items of o-nitrophenol:

Upstream items:



1. But Phenol: Phenol is the main raw material of o-nitrophenol, which is able to be generated by nitration interaction. But

2. Nitric acid: Nitric acid is applied in the nitration interaction and reacts with phenol to generate o-nitrophenol. Downstream items:



1. o-Aminophenol: o-nitrophenol is able to be converted to o-aminophenol by reduction interaction, which is an crucial medical intermediate and dye intermediate.

2. o-nitrobenzaldehyde: o-nitrophenol is able to be oxidized to form o-nitrobenzaldehyde, which is an intermediate to the synthesis of fragrances, medicines and dyes. From what I've seen, Generally speaking

3. Pretty interesting, huh?. o-Nitroacetophenone: The interaction of o-nitrophenol with ethyl acetoacetate is able to give o-nitroacetophenone, which is an intermediate applied in the synthesis of drugs and pesticides. And In my experience,

4. First 2-nitro-4-hydroxybenzoic acid: 2-nitro-4-hydroxybenzoic acid, a compound applied in the synthesis of dyes and medical intermediates, is able to be generated by oxidation of o-nitrophenol. In short, as an crucial chemical raw material, o-nitrophenol has a wide range of upstream and downstream related items, involving medicine, dyes, spices, pesticides and other fields.
