Picric acid, also known as 2,4, 6-trinitrophenol, is an important chemical raw material, widely used in medicine, pesticides, dyes and other industrial fields. The following are some major examples of picric acid upstream and downstream associated products.

upstream products:

1. phenol: phenol is an important raw material for the production of picric acid, through the nitration reaction can produce picric acid.
2. Nitric acid: Nitric acid is used as a nitrating agent in the production of picric acid and reacts with phenol to form picric acid.

downstream products:

1. explosives: picric acid can be used as an explosive component, such as mixed explosives and blasting glue.
2. Dyes: Picric acid can be used in the manufacture of certain dyes, such as yellow dyes and orange dyes.
3. Pharmaceutical intermediates: Picric acid can be used as pharmaceutical intermediates for the production of certain drugs, such as antibacterial drugs and anticancer drugs.
4. Pesticides: Picric acid can be used in the manufacture of certain pesticides, such as insecticides and fungicides.

need to note that picric acid is a toxic and harmful substance, which is harmful to the environment and human health. Therefore, it is necessary to strictly abide by relevant safety regulations and operating procedures during use and production. At the same time, the specific upstream and downstream related products also need to be determined according to different production processes and application areas.
