Piperazines (also known as 1,4-hexahydropyrazines) are saturated analogs of pyrazines. The piperazine ring plays a vital role in biological research and the drug manufacturing industry. A large number of commonly used drugs contain a piperazine moiety, like antianginals, antidepressants, antihistamines, antipsychotics, recreational drugs, urologicals, antihistaminic, anthelmintic, antibacterial, antiallergenic, antiemetic, and antimigraine agents. In general, they can be grouped as phenylpiperazines, benzylpiperazines, benzhydrylpiperazines, pyridinylpiperazines, pyrimidinyl-piperazines, or tricyclics. In addition, piperazine hydrate and piperazine citrate are used as a poultry deworming and a roundworm treatment drug in dogs and cats. Substituted piperazine derivatives occupy an important position both as bioactive targets and useful synthetic intermediates. Piperazine derivatives have also been used in various industries as raw materials for the production of hardeners of epoxy resins, corrosion inhibitors, accelerators for rubber, urethane catalysts, and antioxidants.

Homopiperazines (also known as 1,4-Diazacycloheptane, 2,3,4,5,6,7-Hexahydro-1H-1,4-diazepine) are seven-membered heterocyclic organic compounds with two nitrogen atoms in the 1- and 4-positions. Homopiperazine based compounds have been used as building blocks for several drug molecules owing to their potent biological activities. One of these compounds is 1-methylhomopiperazine, which is used as an intermediate for the preparation of several biologically active compounds. Homopiperazine-based compounds have also been used as corrosion inhibitors.
