• dormex
  • Cyanamide, under the trade name Dormex, is a common agricultural rest-breaking agent applied in spring to stimulate uniform opening of buds, early foliation and bloom. (wikipedia.org)
  • reaction
  • A colourless solid, CaCN 2 , which sublimes at 1300°C. It is prepared by heating calcium dicarbide at 800°C in a stream of nitrogen:CaC 2 (s)+N 2 (g) → CaCN 2 (s)+C(s)The reaction has been used as a method of fixing nitrogen in countries in which cheap electricity is available to make the calcium dicarbide (the cyanamide process).

  • A convenient method for the preparation of secondary amines which are not contaminated with primary or tertiary amines is the reaction of cyanamide with alkyl halides to N,N-dialkylcyanamides which can easily be hydrolyzed to dialkylamines and then decarboxylated. (wikipedia.org)
  • A guanidino group is introduced by reaction of cyanamide with sarcosine In the industrial synthesis of creatine: This synthesis route mostly avoids problematic impurities like chloroacetic acid, iminodiacetic acid or dihydrotriazine that occur in other routes. (wikipedia.org)
  • The Frank-Caro process, also called cyanamide process, is the nitrogen fixation reaction of calcium carbide with nitrogen gas in a reactor vessel at about 1,000°C. The reaction is exothermic and self-sustaining once the reaction temperature is reached. (wikipedia.org)
  • Formula
  • Cyanamide exists as two tautomers, one with the connectivity N≡C-NH2 and the other with the formula HN=C=NH ("carbodiimide" tautomer). (wikipedia.org)
  • Reactions
  • Related reactions exploit the bifunctionality of cyanamide to give heterocycles, and this latter reactivity is the basis of several pharmaceutical syntheses such as the aminopyrimidine imatinib) and agrichemicals Amitrol and hexazinone. (wikipedia.org)
  • make
  • Since the mid-1960s there are methods to stabilize cyanamide in order to make it available on an industrial scale. (wikipedia.org)
  • available
  • Cyanamide is also a versatile synthetic building block for heterocycles: it forms 2-aminobenzimidazole with 1,2-diaminobenzene and it forms with the readily available cyclic enamine 4-(1-cyclohexenyl)morpholine and with elemental sulfur a 2-aminothiazole in good yields. (wikipedia.org)
  • treatment
  • The hair-loss treatment minoxidil and the anthelmintics albendazole, flubendazole, and mebendazole feature 2-aminoimidazole substructures derived from cyanamide. (wikipedia.org)
  • solutions
  • Due to the strong affinity towards self-condensation in alkaline media (see above) solutions of cyanamide are stabilized by the addition of 0.5 wt% of monosodium phosphate as buffer. (wikipedia.org)
  • high
  • BACKGROUND Cyanamide, an aversive drug widely used in Japan, develops ground-glass inclusion bodies in the hepatocytes at high incidences, which may be associated with portal inflammation and fibrosis. (semanticscholar.org)
