2,4-difluoroaniline is an intermediate of organic synthesis. It is used for the synthesis of difluorophenylsalicylic acid and polyhaloperidic acid in medicine. Fluorobenzene salicylic acid is a kind of non steroidal anti-inflammatory drug of carboxylic acid, and the international non exclusive drug name (inn) is diflunisal. The new derivative of salicylic acid, does not contain acetyl group of aspirin, but contains difluorophenyl group, so it has little side effect on platelet and mild gastrointestinal reaction, and its action time can last for 8-12h. Therefore, it may be the most promising salicylic acid drug. It is also an important intermediate of pesticide.

Flunixin meglumine is an organoammonium salt obtained by combining flunixin with one molar equivalent of 1-deoxy-1-(methylamino)-D-glucitol. A relatively potent non-narcotic, nonsteroidal analgesic with anti-inflammatory, anti-endotoxic and anti-pyretic properties; used in veterinary medicine for treatment of horses, cattle and pigs. It has a role as an antipyretic, a non-narcotic analgesic, a non-steroidal anti-inflammatory drug and an EC 1.14.99.1 (prostaglandin-endoperoxide synthase) inhibitor. It contains a flunixin(1-).

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.

Dimetridazole is a C-nitro compound that is 5-nitroimidazole in which the hydrogens at positions 1 and 2 are replaced by methyl groups. An antiprotozoal drug, it has been banned by both the Government of Canada and the European Union as a livestock feed additive owing to suspicions of it being carcinogenic. It has a role as an antiprotozoal drug and an antiparasitic agent. It is a C-nitro compound and a member of imidazoles.

Praziquantel is a kind of anthelmintic for human and animals, which is specially used to treat tapeworms and trematodes. It is especially effective for Schistosoma japonicum, Clonorchis sinensis and Taenia cantonensis. Praziquantel is one of the most important drugs for basic public health in the world.
