Thiophene can be used to make dyes, medicines and resins; Synthesis of a new broad-spectrum antibiotic vancomycin; Used in color film making and special effects photography; Some complex reagents were synthesized; It is an important intermediate in the synthesis of phenolic plastics and resins. Thiophene itself is a good dewaxing agent and paint cleaning agent. Thiophene derivatives have many pharmacological activities. There are many kinds of thiophene azo dyes with excellent properties. Sulfonylurea derivatives of thiophene are new herbicides with super efficiency and low toxicity. Other derivatives can also be used as insecticides, fungicides, plant and animal growth promoters. In addition, some derivatives of thiophene are components of organic semiconductors. In a word, thiophene and its derivatives play an important role in pharmaceutical industry, dye industry, pesticide industry, resin industry, chemical industry and so on.

N. N, n ', n' - tetramethylethylenediamine is a colorless and transparent liquid with a slight smell of ammonia. It is miscible with water, and can be miscible with most organic solvents such as ethanol. It is an important organic intermediate. It is mainly used as biochemical reagent, epoxy resin cross-linking agent and synthesis intermediate of Quaternary amine compounds.

This product is used in organic synthesis, is the intermediate of fungicide allicin.

Piperazine is an organic compound that consists of a six-membered ring containing two opposing nitrogen atoms. First used as a solvent for uric acid, the use of piperazine as an anthelmintic agent was first introduced in 1953. Upon entry into the systemic circulation, the drug is partly oxidized and partly eliminated as an unchanged compound. Outside the body, piperazine has a remarkable power to dissolve uric acid and producing a soluble urate, but in clinical experience it has not proved equally successful. Piperazine was first introduced as an anthelmintic in 1953. Piperazine compounds mediate their anthelmintic action by generally paralyzing parasites, allowing the host body to easily remove or expel the invading organism.

This product is mainly used as the solvent of cellulose acetate, nitrocellulose, shellac varnish and castor oil. It can also be used as solvent for nitrocellulose and intermediate for organic synthesis.
