2,3-Dichloropyridine Usage And Synthesis
Chemical PropertiesWhite to slightly beige crystalline powder
Uses2,3-Dichloropyridine is used as a reagent for the preparation of substituted 3-(5-membered heterocycle-carboxamido)pyridine derivatives for treatment of autoimmune and inflammatory diseases. Also in the synthesis, crystal structure and biological activity of novel anthranilic Diamide insecticide with propargyl ether.
Synthesis 2,3-dichloropyridine is synthesized from 2-chloronicotinic acid via amidation, Hofmann degradation, diazotization and Sandmeyer reaction.
