What is 2-Pyridylacetonitrile?
Chemical properties
Colorless to yellow to orange to brown liquid
The Uses of 2-Pyridylacetonitrile
2-Pyridineacetonitrile is used as a pharmaceutical intermediate. It is also used as an important raw material and intermediate used in organic Synthesis, pharmaceuticals, agrochemicals and dyestuff.
General Description
2-Pyridylacetonitrile undergoes coupling with aromatic diazonium salts to yield arylhydrazones. It also undergoes condensation with active malonic esters to yield 1-cyano-3-substituted 2-hydroxyquinolizin-4-ones. Acylation reaction of 2-pyridylacetonitrile with hot acetic anhydride has been reported.
