| | Pyrazinecarbonitrile Usage And Synthesis |
| Chemical Properties | 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. | | References | [1] Collection of Czechoslovak Chemical Communications, 1996, vol. 61, # 7, p. 1093 - 1101
