Intermediate

1,3,5-Triethylbenzene can be used as an intermediate for pharmaceutical synthesis.

Dimethyl malonate is an important organic synthetic intermediate. It is a colorless liquid obtained by the esterification reaction of malonic acid and methanol. It has a wide range of applications in pharmaceuticals, dyes, fragrances and other fields, and is commonly used for the synthesis of barbiturates (such as barbituric acid) and the key pharmaceutical raw material pipemidic acid.

It can be used as a preservative in food, feed, latex and toothpaste.
It can be used as a fixative for fruit juices and beverages.
It can serve as a mordant for dyeing and printing.
It can be applied as a plasticizer for plastics.
It acts as an antimicrobial agent.

Malononitrile is the raw material for synthesizing 2-amino-4,6-dimethoxypyrimidine and 2-chloro-4,6-dimethoxypyrimidine. It is applied to produce sulfonylurea herbicides such as bensulfuron-methyl, pyrazosulfuron-ethyl, as well as herbicide bispyribac-sodium. In pharmaceutical industry, it is used for diuretic drugs, synthesis of Vitamin B1, aminopterin, triamterene and other vital medicines. Besides, it can be utilized as extractant for gold.

Piperazine, also known as piperazidine or antepar, is an organic compound with the chemical formula C4H10N2. It serves as a significant pharmaceutical intermediate.

It is mainly used as a crosslinking agent for water-based adhesives and water-based latexes. It is widely applied in synthetic emulsion binders and self-crosslinking emulsion polymers. It can also be used for fiber modification, resin processing, as well as treating agents for paper, leather and metal surfaces. Additionally, it can be utilized in soil conditioners and other fields. As an organic synthetic monomer, it can be employed to prepare various copolymers.

Benzylamine is a colorless oily liquid and alkaline. White crystals precipitate when exposed to air on standing.

HPMC is a semi-synthetic nonionic cellulose mixed ether that usually appears as a white or white-like powder. It is prepared by chemical modification of natural cellulose.

p-Aminobenzoic acid is one component of folic acid, a substance essential for the growth and division of human body cells. It can be used as a chemical reagent and raw material for organic synthesis, as well as an intermediate for azo dyes. It is applied to manufacture dyes including Reactive Red M-80, M-10B and Reactive Red Violet X-2R, together with cyanobenzoic acid and the pharmaceutical agent p-carboxybenzylamine. It also functions as a sunscreen; its derivative octyl dimethylaminobenzoate is an excellent UV filter.
