Intermediates are made from cyclic compounds such as benzene, naphthalene, anthracene, etc. through sulfonation, alkali melting, nitrification, reduction and other reactions. For example, benzene is nitrified to nitrobenzene, and then reduced to aniline, which can be chemically processed into dyes, drugs, vulcanization accelerators, etc. Nitrobenzene and aniline are both 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, butadiene can be chemically processed into synthetic rubber, synthetic fiber, etc. Butadiene is an intermediate.
Pharmaceutical intermediate production requires a large number of special chemicals. Most of these chemicals were originally produced by the pharmaceutical industry. However, with the deepening of the social division of labor and the advancement of production technology, the pharmaceutical industry 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.
We, chemical intermediate manufacturer, can supply GC methyl thioglycolate, 5-Chloro-2-pentanone CAS 5891-21-4 and methacrylatoethyl trimethyl ammonium chloride, and so on.
