Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of certain vitamins and drugs where pyridine derivatives are required. It serves as a building block in organic reactions, especially in the development of agrochemicals and fine chemicals. Its oxidized structure enhances reactivity in catalytic and coupling reactions, making it valuable in research laboratories and industrial processes for creating nitrogen-containing heterocyclic compounds. Also employed as a ligand or modifier in coordination chemistry and catalysis due to its ability to stabilize metal complexes.
