GUANIDINE Chemische Eigenschaften,Einsatz,Produktion Methoden
Verwenden
Two derivatives of guanidine, dodine (27) and iminoctadine
(28), are being used as agricultural fungicides
. The former was reported in 1957 (28), whereas the latter is new as a member of the multisite inhibitor group of fungicides. Both have one or two guanidine group(s) connected to a long chain alkyl or iminodi( polymethylene) group and seem to belong to a kind of cationic surface active agent.
Definition
guanidine: A crystalline basic compoundHN:C(NH
2)
2, related to urea.
Biologische Funktion
Guanidine hydrochloride is the drug of choice in the
management of patients with myasthenic syndrome and
may be of use in the treatment of botulinum intoxication.
Its ability to enhance transmitter release may involve a
block of K
+ channels and prolongation of the nerve action
potential.
Landwirtschaftliche Anwendung
Guanidine, a colorless crystal with a melting point of 50°C, is soluble in water and alcohol. It is an analogue of urea and is also known as amino urea. Guanidine synthesis occurs by treating urea with ammonia under pressure or by heating calcium cyanamide with ammonium iodide.
Guanidine forms a number of salts like the carbonate, phosphate, nitrate, sulphate and hydrochloride which can be used as fertilizers.
