Examples
By Part of Speech
adjective
British English
- The cyanoguanidine sample was analysed by HPLC.
- We need a high-purity cyanoguanidine source.
American English
- The cyanoguanidine reaction yielded a new polymer.
- Check the cyanoguanidine concentration in the mixture.
Examples
By CEFR Level
- The factory produces cyanoguanidine for use in fertilisers.
- Cyanoguanidine is listed as a key ingredient in the patent.
- The researchers successfully synthesised the novel pharmaceutical intermediate via a condensation reaction using cyanoguanidine.
- Cyanoguanidine's slow-release nitrogen properties make it a valuable component in certain agricultural formulations.
Learning
Memory Aids
Mnemonic
Think: 'CYAN' (as in cyanide/blue-green) + 'GUAN' (as in guano, a source of nitrogen) + 'IDINE' (a common chemical suffix). It's a nitrogen-rich (like guano) chemical compound.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate as 'циан' + 'гуанидин' separately. The established Russian term is 'дициандиамид' (ditsiandiamid) or 'цианогуанидин' (tsianoguanidin).
Common Mistakes
- Misspelling as 'cyano-guanadine', 'cyanoguanadine', or 'cyanoguanadine'.
- Confusing it with 'cyanamide' (its precursor monomer).
- Using it outside of a chemical context where it would be incomprehensible.

FAQ
Frequently Asked Questions
As with many industrial chemicals, it requires proper handling. Refer to its Safety Data Sheet (SDS) for specific hazards, which may include irritation and environmental effects.
Its primary uses are as a chemical intermediate in producing pharmaceuticals, explosives, dyes, fertilizers (as a slow-release nitrogen source), and flame retardants.
Cyanamide (NH2CN) is a simpler molecule. Cyanoguanidine (C2H4N4), or dicyandiamide, is formed by the dimerization (joining of two molecules) of cyanamide.
No. This is a highly specialized technical term. Knowledge is generally limited to chemists, chemical engineers, and professionals in related manufacturing or research fields.
