knorr pyrazole synthesis applications

Pyrazole can also be used as the side chain of some photosensitive monomers. In addition, Pyrazole is also used as a halogen-containing Solvent, lubricant stabilizer, chelating agent, organic synthesis intermediate. Pyrazole, also known as 1,2-diazoles, Diazene Pentacyclines, o-diazepines; is White needle-shaped or prismatic crystal, from ethanol crystallization of pyrazole is colorless needle-shaped crystal. Pyridine-like odor and pungent bitter taste, soluble in water, alcohol, ether and benzene. The boiling point and melting point of the compounds increased when there were substituents on the carbon atoms, and decreased when there were substituents on the nitrogen atoms. Chlorination, bromination, iodination, alkylation and acylation are easy to occur. The formula is C3H4N2. Indicators Electronic grade Pharmaceutical grade Pestic…
