Piperazine Usage And Synthesis
Important pharmaceutical intermediatesPiperazine is an important pharmaceutical intermediate, is mainly used for the production of anthelmintic piperazine phosphate, piperazine citrate and fluphenazine, strong pain, rifampicin, adipic acid piperazine, piperazine guanidine methyl tetracycline, quinoline piperazine phosphate, piperazine thiazole nitrate, enoxacin, hydroxyzine hydrochloride, trifluoperazine, diethylcarbamazine citrate, cinnarizine, flunarizine, decloxizine strong carbamazepine, prednisolone sodium phosphate, dexamethasone sodium phosphate, PPA, norfloxacin, ciprofloxacin, easy to cough piperazine, a piperazine Lee vancomycin, trimethoprim-triazine and other drugs. It is Also used for the production of surfactants products such as wetting agents, emulsifying agents,and dispersing agents ,and the production of plastic additives such as antioxidants, preservatives, stabilizers and rubber additives. It is derived from Dichloroethane by alcohol solution of ammonia.
The structural formula of piperazine
Figure 1 The structural formula of piperazine.
Pharmacology and mechanism of actionPiperazine is a heterocyclic organic base widely used as an anthelminthic. It was originally developed for the treatment of gout. Its first successful use in helminthiasis was reported by Mouriquand et al. in 1951 [1]. Presently the drug is used in the treatment of infections caused by Ascaris lumbricoides and Enterobius vermicularis.
The drug causes flaccid paralysis in susceptible worms and the parasites lose their attachment to the intestinal wall, and are swept away by the normal bowel peristalsis. The biochemical mechanism behind this action is uncertain. Piperazine causes hyperpolarization of the Ascaris muscle rendering it unresponsive to acetylcholine [2].
IndicationsTreatment of infections due to Ascaris lumbricoides and Enterobius vermicularis. When cost and availability are not a consideration, safer and more effective drugs such as mebendazole or albendazole should be used instead.
Side effectsSide effects commonly encountered with the recommended doses of piperazine are nausea, vomiting, abdominal cramps and diarrhoea which are usually mild and self-limiting. Although absolute incidence is unknown, severe side effects reported in the literature are rare. They can be classified into:
1. Allergic reactions such as urticaria, exantema, hypersensitivity, lacrimation, rhinorrea, productive cough, and bronchospasm[3,4].
2. Neuro-psychological reactions[5-11]:
(a) cerebral type such as vertigo, dizziness, tremor, incoordination, ataxia and hypotonia with EEG changes;
(b) psychic type such as depersonalization, hallucination and paranoic reactions;
(c) miscellaneous such as headache, visual disturbances, somnolence, coma and an increase in the number of petit mal attacks.
Neuro-psychological reactions are rare. Most cases reported concern children with pre disposing factors like neurological symptoms, renal diseases or those who have been treated with high doses of piperazine.
One case of haemolytic anaemia in a patient with G6PD deficiency [12], and one case of toxic hepatitis[13] have also been reported. However, no causal relationships can be established from these cases.
Nitrosation of piperazine to the potential carcinogen N-mononitrosopiperazine in the stomach of patients treated with normal therapeutic doses has been reported[14]. However, carcinogenicity related to the use of piperazine has not been reported despite the use of the drug over many years. In any case, this is unlikely to have any clinical implications with the short treatment period of nematodes.
Contraindications and precautionsPiperazine should not be given to patients with hypersensitivity or with neurological diseases,especially epileptic patients.
InteractionsIn rats and mice, piperazine 1–5 g/kg subcutaneously, potentiates the side effects of chlorpromazine [15]. However, this is unlikely to have any clinical significance. Piperazine is antagonistic to pyrantel, bephenium and levamisole , but no potential clinical interactions have been reported.

General DescriptionNeedle-like white or colorless crystals. Shipped as a solid or suspended in a liquid medium. Very corrosive to skin, eyes and mucous membranes. Solid turns dark when exposed to light. Flash point 190°F. Used as a corrosion inhibitor and as an insecticide.
Air & Water ReactionsFlammable. Absorbs water and carbon dioxide from air. Soluble in water.
Reactivity Profile1,4-Diazacyclohexane neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Absorbs carbon dioxide from the air, which can cause dry crystals to seem to melt. May generate hydrogen, a flammable gas, in combination with strong reducing agents such as hydrides. 1,4-Diazacyclohexane is sensitive to light; 1,4-Diazacyclohexane absorbs water and carbon dioxide from air. 1,4-Diazacyclohexane may be corrosive to aluminum, magnesium and zinc. .
Health HazardTOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
Fire HazardCombustible material: may burn but does not ignite readily. When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form.
Contact allergensPiperazine is contained in pyrazinobutazone, an equimolar salt of piperazine and phenylbutazone. Among occupational cases, most were reported in the pharmaceutical industry or laboratory workers, in nurses, and in veterinarians.
Purification MethodsPiperazine crystallises from EtOH or anhydrous *benzene and is dried at 0.01mm. It can be sublimed under vacuum and purified by zone melting. The hydrochloride has m 172-174o (from EtOH), and the dihydrochloride crystallises from aqueous EtOH and has m 318-320o (dec, sublimes at 295-315o). The picrate has m ~200o, and the picrolonate crystallises from dimethylformamide ( m 259-261o). [Beilstein 23 H 4, 23 I 4, 23 II 3, 23 III/IV 15, 23/1 V 30.]
