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
