Uses
It is used as a one day wormer, either in water or feed, for the control of Round worms in poultry, swine, and horses. It also controls nodular worms in swine, and small strongyles in horses.
General Description
White to cream-colored needles or powder. Mp: 318-20°C (with decomposition).
Reactivity Profile
PIPERAZINE DIHYDROCHLORIDE is incompatible with the following: Water, HEAT, flames, oxidizers. PIPERAZINE DIHYDROCHLORIDE absorbs moisture from air. PIPERAZINE DIHYDROCHLORIDE may create flammable condition upon contact with HEAT, FLAMES and OXIDIZERS.
Safety Profile
Moderately toxic by intraperitoneal route. Mildly toxic by ingestion. When heated to decomposition it emits very toxic fumes of NOx and HCl. Used in making fiber, pharmaceuticals, and insecticides. See also PIPERAZINE.
Potential Exposure
Agricultural chemical, Suspected reprotoxic hazard. Piperazine is used to manufacture anthelmintics, antifilarials, antihistamines, and tranquilizers; the dihydrochloride is used in the manufacture of fibers, pharmaceuticals and insecticides. They are used as an intermediate in the manufacture of, pesticides, rubber chemicals and fibers. Also, piperazine is widely available, effective, and safe when used on an occasional basis against ascaride infections. It is also considerably cheaper than other anthelminthic drugs. In some countries where ascariasis is not endemic and where piperazine was used predominantly for the treatment of pinworn, it has been withdrawn from use on the grounds that other effective drugs are now available. Clinical dosages occasionally induce transient neurological signs and, in some circumstances, the drug may generate small amounts of nitrosamine in the stomach, which at considerably greater dosage in experimental animals has been demonstrated to have a carcinogenic potential.
Purification Methods
Crystallise the salt from aqueous EtOH and dry it at 110o. [Beilstein 23 III/IV 17, 23/1 V 30.]
Incompatibilities
Aqueous solution is a strong base. Violent reaction with strong oxidizers and dicyanofurazan. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides, nitrogen compounds, carbon tetrachloride. Attacks aluminum, copper, nickel, magnesium and zinc.
