Piperazine is widely used in the pharmaceutical industry as an anthelmintic agent, effectively treating parasitic worm infections such as roundworms and pinworms in humans and animals. It works by paralyzing the worms, allowing them to be expelled from the body through feces. Additionally, it has been used in the treatment of certain urinary tract infections. It serves as a building block in the synthesis of various drugs, including antihistamines, antipsychotics, and agrochemicals. In the chemical industry, piperazine is utilized as a corrosion inhibitor and in the production of polymers, plastics, and resins. It also acts as a catalyst in certain organic reactions, enhancing efficiency in manufacturing processes.
