Mr. Martin
What can I do for you?
Pharmaceutical Intermediates are actually some chemical raw materials or products used in the synthesis process. Chemical products do not need that kind of production license. They can be produced in ordinary chemical plants. As long as they reach some grades, they can be synthesized appropriately.
Types of intermediates
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 intermediates to save costs.
Intermediates are formed from cyclic compounds such as benzene, naphthalene, anthracene, etc. through sulfonation, alkali fusion, nitration, reduction, etc. 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 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 is dehydrogenated to butadiene, which can be chemically processed into synthetic rubber, synthetic fibers, and the like.
Butadiene is an intermediate.
It originally refers to the intermediate products produced in the process of synthesizing chemical products such as spices, dyes, resins, drugs, plasticizers, rubber accelerators, etc. using coal tar or petroleum products as raw materials. It now generally refers to various intermediate products obtained in the process of organic synthesis.
