Aspect Details
Name 3-Amino-4-pyrazolecarbonitrile
Common Synonyms 4-Cyanopyrazol-3-amine
CAS No. 1003-30-7
Molecular Formula C₄H₃N₅
Molecular Weight 109.10 g/mol
Physical Properties
  • Appearance: White to light-yellow crystalline solid
  • Melting Point: 220-222 °C (decomposes)
  • Solubility: Slightly soluble in water; soluble in polar organic solvents like DMF and DMSO
  • Density: Not explicitly stated but estimated to be approximately 1.4-1.5 g/cm³
Chemical Properties Contains an amino group (-NH₂) and a nitrile group (-CN) on a pyrazole ring. The amino group offers basicity and nucleophilic reactivity, while the nitrile group can undergo hydrolysis or reduction. The pyrazole ring structure contributes to aromaticity and resonance stabilization.
Applications
  • Used as a key intermediate in pharmaceutical synthesis, particularly in the development of antiviral and anticancer drugs
  • Employed in agrochemicals for the synthesis of herbicides and fungicides
  • Acts as a building block for fluorescent dyes and ligands in coordination chemistry
Safety Information
  • Handle with appropriate protective equipment to avoid inhalation and skin contact
  • Store in a cool, dry, and well-ventilated area away from incompatible materials
