Definition of cyanamide in English: cyanamidenoun sʌɪˈanəmʌɪd mass nounChemistry 1A weakly acidic crystalline compound made as an intermediate in the production of ammonia. Alternative name: cyanogen amide; chemical formula: CH₂N₂ Example sentencesExamples - Hydrogen cyanamide reduced fruit set in the first year but not the second.
- Enzymatic activity in extracts of a soil fungus, Myrothecium verrucaria, hydrates the nitrile group of cyanamide with formation of urea.
- Yabuki et al. described a novel metabolite with a different ring-opening pattern leading to a cyanamide.
- It re-examined the approval to import and manufacture soluble concentrates containing hydrogen cyanamide to ensure existing controls were adequate to address potential risks.
- Under this scenario, dormancy-breaking chemicals (such as hydrogen cyanamide, HC) enhance budbreak by diminishing the duration of suppression.
- 1.1 A salt of cyanamide containing the anion CN₂²⁻, especially the calcium salt used as a fertilizer.
Example sentencesExamples - The reactivity of the nitrile functional group in calcium cyanamide makes it as a chief industrial raw material.
- No information is available on the reproductive or developmental effects of calcium cyanamide in humans or animals.
Origin Mid 19th century: blend of cyanogen and amide.
