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.

Allicin is an antibacterial substance, which can inhibit the growth and reproduction of dysentery bacilli, typhoid bacilli and Vibrio cholerae. It has obvious inhibition and killing effect on Staphylococcus, Streptococcus and pneumococcus, so it can reduce the incidence rate of chicken and fish. Adding a small amount of allicin to the feed of chickens, ducklings and layers can improve the survival rate of livestock chickens and ducklings and the laying rate of layers. Adding allicin to broilers and ducks can improve the feed utilization rate by 6% - 16%, improve the feed palatability, stimulate oral taste buds and increase animal feed intake. Allicin can improve the flavor of chicken and duck. For fish, allicin is mainly used for disease prevention, treatment and good food attractant. At the same time, it can also combine the added vitamin B1 with garlic thiamine to prevent the decomposition of vitamin B1 by vitamin B2 decomposition enzyme in live bait (FISH). Garlic thiamine has the same effect as vitamin B1, but its absorption is better than vitamin B1 and its physiological effect is better. Therefore, allicin can also prevent fish vitamin B1 deficiency, reduce feed coefficient and promote fish growth.

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.

3-methyl-2-nitrobenzoic acid is an organic synthetic intermediate and pharmaceutical intermediate, which can be used in laboratory R & D process and chemical production process.
