What is Piperazine?

Piperazine is an azacycloalkane that consists of a six-membered ring containing two nitrogen atoms at opposite positions. It has a role as an anthelminthic drug. It is a member of piperazines, a saturated organic heteromonocyclic parent and an azacycloalkane. It is a conjugate base of a piperazinium(2+).
