Lufenuron is the active ingredient in the veterinary flea control medication Program, and one of the two active ingredients in the flea, heartworm, and anthelmintic medicine milbemycin oxime/lufenuron (Sentinel). Lufenuron is stored in the animal's body fat and transferred to adult fleas through the host's blood when they feed. Adult fleas transfer it to their growing eggs through their blood, and to hatched larvae feeding on their excrement. It does not kill adult fleas.; Lufenuron, a benzoylurea pesticide, inhibits the production of chitin in insects. Without chitin, a larval flea will never develop a hard outer shell (exoskeleton). With its inner organs exposed to air, the insect dies from dehydration soon after hatching or molting (shedding its old, smaller shell).; Lufenuron is also used to fight fungal infections, since fungus cell walls are about one third chitin. Lufenuron is also sold as an agricultural pesticide for use against lepidopterans, eriophid mites, and western flower thrips. It is an effective antifungal in plants.

Ethyl bromoacetate is used in organic synthesis, mainly in pharmaceutical and pesticide intermediates. It can also be used to make military poison gas.

P-chlorotoluene is the intermediate of fenvalerate, Paclobutrazol, Uniconazole, trifluralin, chlorpyrifos, and so on. It can also be used to produce p-chlorobenzaldehyde, which is used as dye and pharmaceutical intermediate. The p-chlorobenzoyl chloride is the intermediate of xiaoyantong, and the p-chlorobenzoic acid is the raw material of dye and textile finishing agent.

Tebuconazole is a triazole fungicide. It is a high-efficiency fungicide used for seed treatment or leaf spraying of important economic crops. It can also conduct to the top of the object and kill the bacteria in the object. Its bactericidal mechanism is mainly to inhibit the biosynthesis of ergosterol of pathogenic bacteria, and can prevent and control diseases caused by powdery mildew, stem rust, coracospora, nuclear cavity bacteria and chaetospora. At present, it is used as seed treatment agent and foliar spray all over the world. It has broad spectrum of bactericidal activity, high activity and long duration. It is mainly used to control a variety of fungal diseases on wheat, rice, peanuts, vegetables, bananas, apples, pears, corn sorghum and other crops.

N-Methylmorpholine is an important fine chemical product. It is an excellent solvent, emulsifier, corrosion inhibitor, polyurethane foam catalyst, and can also be used as pesticide intermediate. It is also used in the synthesis of surfactant, lubricant coolant, metal antirust agent, fiber treatment agent and other fine chemical products. The main synthesis methods are N-methylation method using morpholine as raw material, cyclization method using diethanolamine as raw material, cyclization method using diethanolamine as raw material and synthesis method using dichloroethane as raw material.
