(3-CHLORO-PYRIDIN-2-YL)-HYDRAZINE Usage And Synthesis

Uses

3-chloro-2-hydrazino pyridine is the important intermediate of synthesizing new ryania acceptor sterilant Rynaxypyr (Chlorantraniliprole) and cyanogen insect amide (Cyantraniliprole).

Synthesis

2, 3-dichloropyridine and hydrazine hydrate mix, add polar solvent, after back flow reaction 4-8 hour, reduce to the room temperature suction filtration promptly, yield of 3-chloro-2-hydrazino pyridine is 95%-99%.
