Applications & Uses
Uses
2,4-Dichloropyridine is a versatile reactant used in the preparation of host materials for light-emitting diodes with heterocyclic cores. Also used in the preparation of sulfonylated pyridines, pyrazine and quinoline via aromatic nucleophilic substitution of azines with sodium sulfinates.
