Reaction intermediates in organic chemistry referred to as organic intermediates，intermediates are also called organic intermediates. Use coal tar or petroleum products as raw materials to manufacture intermediate products such as dyes, pesticides, medicines, resins, additives, and plasticizers. Because it was originally used to make dyes, it is also called dye intermediates.
Types of Intermediate in Organic Chemistry
Organic Intermediates refer to semi-finished products, which are intermediate products in the production of certain products. For example, to produce a product, it can be produced from organic intermediates to save costs.
Organic Intermediates are formed from cyclic compounds such as benzene, naphthalene, anthracene, etc. through sulfonation, alkali fusion, nitration, reduction and other reactions. For example, benzene is nitrated to nitrobenzene, and then reduced to aniline, which can be chemically processed into dyes, drugs, vulcanization accelerators, etc. Both nitrobenzene and aniline are organic intermediates.
There are also acyclic compounds such as methane, acetylene, propylene, butane, butene, etc. through dehydrogenation, polymerization, halogenation, hydrolysis and other reactions. For example, butane or butene can be dehydrogenated into butadiene, and butadiene can be chemically processed into synthetic rubber and synthetic fibers. Butadiene is an organic intermediate.
Initially, it refers to the organic intermediate products produced in the process of using coal tar or petroleum products as raw materials to synthesize chemical products such as spices, dyes, resins, drugs, plasticizers, and rubber accelerators. Now generally refers to various organic intermediate products obtained in the process of organic synthesis.

Organic Intermediate Pharmaceutical Supplies
The so-called pharmaceutical intermediates are actually some chemical raw materials or chemical products used in the process of drug synthesis. This kind of chemical product does not require a pharmaceutical production license and can be produced in an ordinary chemical plant. As long as it reaches a certain level, it can be used for the synthesis of pharmaceuticals.
Pharmaceutical production requires a large number of special chemicals. Most of these chemicals were originally produced by the pharmaceutical industry. However, with the deepening of social division of labor and the advancement of production technology, the pharmaceutical industry has transferred some pharmaceutical intermediates to chemical companies for production. Pharmaceutical intermediates are fine chemical products, and the production of pharmaceutical intermediates has become a major industry in the international chemical industry.
In cell biology, the intermediate refers to the middle part of the spindle that is gradually disintegrated near the equatorial plane in the late stage of cell division. The surrounding cytoplasm concentration increases and fills the entire equatorial plane. This thickened area is called the intermediate.
Application of organic intermediates
- O-chlorobenzoic acid
Anti-mold agent, it can prevent the clothes from becoming moldy and rotting. The main raw material to make it is an intermediate-o-chlorobenzoic acid. Ortho-chlorobenzoic acid is an important intermediate in pesticide, pharmaceutical and dye industries with a wide range of uses. It is mainly used in the synthesis of pesticides (Su Urea No. 1) and antifungal agents in pesticides, and is mainly used in the synthesis of pesticides. The antipsychotic drugs perphenazine, the adrenal gland drugs Zengrubensin and Chuantong, the antifungal drugs clotrimazole, chlorpromazine, ketamine and diclofenac, are standard reagents for alkalimetry and iodometry, used as adhesives And paint preservatives. In addition, it also plays a major role in dyes. We cannot do without taking photos every day. Everyone has their own photos. The main body of the photo is film, and the main body of the film can be made of o-chlorobenzoic acid. In chemistry, isomers often have similar chemical properties, so p-chlorobenzoic acid also has similar functions to o-chlorobenzoic acid, and is also an intermediate of pesticides and pharmaceutical dyes. Because of them, life has more colorful beauty and memories that can last forever. Promote the progress of life and improve the quality of life.
In contemporary life, mobile phones, TVs, refrigerators, and cars have become an important part of our lives. These products have brought many conveniences and excitements to our lives. Using mobile phones, you can chat and talk with friends and relatives in different places through a thin layer of display screen. With TV, you can watch the customs and beautiful scenery all over the world, and you can learn and entertain. The use of refrigerators prolongs the freshness time of food, and the use of cars makes us walking faster and more comfortable. An important part of these products is biphenyl diphenol. Biphenyldiol is an important organic intermediate, which can be used as rubber antioxidant and plastic antioxidant, as well as colorless vulcanized rubber products, food packaging rubber products and medical latex products. The tires on the vehicles we ride, the plastic bags we use for shopping, the table tennis bats for entertainment, the rubber seals on the food packaging mouths, and the medical gloves in the hospital can all be made of dihydroxybenzene. In terms of synthetic polymers, due to its excellent heat resistance, it can be used as a modified monomer of polyester, polyurethane, polycarbonate, polysulfone and epoxy resin to produce excellent engineering plastics and composite materials. Wait. In automobiles, engineering plastics are mainly used as bumpers, fuel tanks, dashboards, body panels, doors, lamp covers, fuel pipes, radiators, and engine-related parts; in machinery, engineering plastics can be used for bearings, gears, Screw nuts, seals and other mechanical parts and housing, cover plates, handwheels, handles, fasteners and pipe joints and other mechanical structural parts; in electronic appliances, engineering plastics can be used for wire and cable coating, printed circuit boards , Insulating film and other insulating materials and structural parts of electrical equipment; in household appliances, engineering plastics can be used in refrigerators, washing machines, air conditioners, TV sets, electric fans, vacuum cleaners, electric irons, microwave ovens, rice cookers, radios, and sound systems. Equipment and lighting appliances; in the chemical industry, engineering plastics can be used in chemical equipment such as heat exchangers, chemical equipment linings, and pipes and pipe fittings, valves, pumps and other chemical pipelines. In addition to these, its high-purity products are mainly used to synthesize liquid crystal polymers. Mainly used to make LCD screens for mobile phones, TVs and other electronic products.
