As an important chemical raw material, o-chloroaniline is widely used in pesticides, pharmaceuticals, dyes and other fields. Its upstream and downstream related products are numerous, and some of the main upstream and downstream products will be described in detail below.

upstream products:

1. Aniline: Aniline is one of the important raw materials of o-chloroaniline, which can be produced by chlorination reaction.

2. Chlorine gas: Chlorine gas is another important raw material in the production process of o-chloroaniline, which is used for substitution reaction with aniline to generate o-chloroaniline.

downstream products:

1. pesticides: o-chloroaniline can be used to produce a variety of pesticides, such as fungicides, insecticides, etc. Among them, chlorothalonil, a fungicide produced from o-chloroaniline, is a broad-spectrum, high-efficiency and low-toxicity pesticide, which is widely used in the prevention and control of diseases and insect pests of fruit trees, vegetables, grains and other crops.

2. pharmaceutical intermediates: o-chloroaniline can be used as pharmaceutical intermediates for the production of a variety of drugs, such as anti-tuberculosis drugs, anti-tumor drugs. Among them, the anti-tuberculosis drug isoniazid produced from o-chloroaniline is a widely used drug and has a good inhibitory effect on tuberculosis bacteria.

3. Dyes: o-chloroaniline can also be used to produce a variety of dyes, such as cationic dyes, acid dyes, etc. These dyes are widely used in textile, printing and dyeing, papermaking and other industries.

In short, as an important chemical raw material, o-chloroaniline has a wide range of upstream and downstream related products, which is of great significance for promoting the development of pesticides, pharmaceuticals, dyes and other industries.
