Ortho-nitrochlorobenzene is an important organic chemical raw material, which is widely used in medicine, pesticides, dyes and other fields. There are many upstream and downstream related products, and several major related products are described in detail below.

1. Upstream product

The main upstream raw materials of o-nitrochlorobenzene are benzene, nitric acid and chlorine. Benzene is a common organic compound, which widely exists in nature and industrial production. Nitric acid and chlorine are common chemical raw materials, which can be used for oxidation and chlorination reactions.

2. Downstream products

(1) anthranilic acid

o-nitrochlorobenzene can be used to prepare anthranilic acid by reduction reaction, which is an important pharmaceutical intermediate and can be used to produce anti-tuberculosis drugs, Antibacterial drugs, etc.

(2) o-nitroaniline

o-nitrobenzene chloride can also be prepared by reduction reaction o-nitroaniline, which is an important dye intermediate, which can be used to produce yellow, orange, red and other dyes.

(3) o-phenylenediamine

o-nitrobenzene chloride can be prepared by reduction, acidification and other steps, which is an important pesticide intermediate and can be used to produce fungicides, herbicides and other pesticides.

In short, as an important organic chemical raw material, o-nitrochlorobenzene has a wide range of upstream and downstream related products, involving medicine, pesticides, dyes and other fields.
