Application of 113770-88-0, With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.113770-88-0, name is 3-Fluoro-4-cyanopyridine, molecular formula is C6H3FN2, molecular weight is 122.1, as common compound, the synthetic route is as follows.
3-Fluoro-isonicotinonitrile (0.50 g, 4.10 mmol) was dissolved in ethanol (8 mL) and treated with hydrazine hydrate (0.31 g, 6.1 mmol). After stirring at 70 C for 16 h, the mixture was cooled to RT and concentrated in vacuo and dried to yield the title compound (0.66 g, 100% of theory). LC-MS (Method 2B): Rt = 0.51 min, MS (ESIPos): m/z = 135 [M+H]+
The chemical industry reduces the impact on the environment during synthesis 113770-88-0, I believe this compound will play a more active role in future production and life.
