Colorless liquid | [Uses]
Pyrazinenitrile (Pyrazinamide EP Impurity) is used as a single-source precursor in the synthesis of metal-free nitrogen-doped carbon nanoparticles (NCNPs). Also, it is an important intermediate in the production of pyrazinamide as an effective anti-tubercular drug. | [Definition]
ChEBI: Cyanopyrazine is a member of pyrazines and a nitrile. | [Synthesis]
2-cyanopyrazine was prepared from 2-methylpyrazine with iron phosphate catalyst by vapor phase catalytic ammoxidation in a fixed-bed reactor. |
