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.

  The Silica Sol process is used to cast complex high quality parts with requirements of a very good surface finish and close dimensional tolerances.Â
This process can range from a weight of just a few ounces to approximately 80 pounds. If you are concerned with precision in very small parts, we are especially proficient at very fine detail work including teeth and serrations.
  The water glass process is typical of the process in the early stages of investment castings. It generally is capable of much larger castings than the Silica Sol process, but does not have as good of surface finish or tolerances. The water glass process provides parts that have better surface finish and dimensional tolerances than sand castings.
This process may range in weight from several ounces to approximately 200 pounds.
We have the capacity to provide OEM, ODM service. We can provide casting, machining, heat treatment, surface treatment service according to your drawings, ideas or samples.
