Pyrazinecarbonitrile Chemical Properties,Usage,Production

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.
