Pesticide Intermediates

1-Ethylpiperazine is one of the piperazine series products. It is an important fine chemical. It is the intermediate of synthetic medicine and synthetic pesticide. It is mainly used for the synthesis of ethyl ciprofloxacin antibacterial drugs. It is also used as the raw material for the synthesis of dyes, plant protectants and other products. In addition, it is also widely used in bactericides and surfactants.

α- Ethyl chloropropionate is an intermediate of herbicide quizalofop. It can be used as intermediate of pesticide, medicine and perfume.

1,3-Dichlorobenzene is an organic compound with the formula C6H4Cl2. It is the least common of the three isomers of dichlorobenzene, it is a colorless liquid that is insoluble in water. It is produced as a minor byproduct of the chlorination of benzene, but can also be prepared in a directed manner by the Sandmeyer reaction of 3-chloroaniline. It also arises from the isomerization of the other dichlorobenzenes at high temperature.Used in organic synthesis. The Friedel-Crafts reaction between m-dichlorobenzene and chloroacetyl chloride yields 2,4,ω-trichloroacetophenone, which is used as an intermediate for the broad-spectrum antifungal drug miconazole. The chlorination reaction is carried out in the presence of ferric chloride or aluminum mercury, and 1,2,4-trichlorobenzene is mainly produced. In the presence of a catalyst, it is hydrolyzed at 550-850°C to produce m-chlorophenol and resorcinol. Using copper oxide as a catalyst, it reacts with concentrated ammonia at 150-200°C under pressure to generate m-phenylenediamine. 2. Used in dye manufacturing, organic synthesis intermediates and solvents.

This product can be used to manufacture a variety of pesticides, fungicides and herbicides. It is an important intermediate of medicine and pesticides.

Nitroguanidine is an organic synthetic raw material. It is used as an intermediate of imidacloprid and Acetamiprid in pesticides to synthesize the next intermediate n-nitroimino imidazolidine. In addition, it can be reduced to prepare aminoguanidine, which can be used to synthesize angina pectoris drug lecoan, etc. it can also be used in the preparation of explosives and smokeless water drugs.
