piperazin

Piperazine is an organic compound with the chemical formula C4H10N2. It is a cyclic diamine, meaning it contains two amine functional groups within a six-membered ring structure. Piperazine is a colorless, hygroscopic solid that is soluble in water and organic solvents. It has a distinctive ammonia-like odor.

Industrially, piperazine is primarily manufactured from ethylenediamine or ethanolamine. It finds extensive use as a building block in the synthesis of various organic chemicals. Its most significant application is in the pharmaceutical industry, where it serves as a core structure for a wide range of drugs. These include anthelmintics, used to treat parasitic worm infections, and antipsychotic medications.

Beyond pharmaceuticals, piperazine and its derivatives are employed in the production of polymers, such as polyamides and polyurethanes. They are also utilized as corrosion inhibitors, particularly in boiler systems and cooling towers, and as catalysts in certain chemical reactions. In some niche applications, piperazine has been explored as a component in carbon capture technologies due to its ability to absorb carbon dioxide. The handling of piperazine requires care, as it can be irritating to skin and eyes.
