Piperazine is a strong base. It is obtained by hydrogenation of pyrazine or 2,5-piperazinedione or condensation of dibromo-ethane with ammonia. Piperazine and its derivatives are used in analytical chemistry for microcrystalloscopic identification of Mo, V, and W and in medicine (in the form of salts of adipinic, citric, phosphoric, or sulfuric acid) as an anthelmintic in cases of ascariasis and enterobiasis.
