1-Methyl-2-oxo-1,2-dihydropyridine-4-carbonitrile is primarily used in organic synthesis as a key intermediate for the preparation of various heterocyclic compounds. Its structure makes it valuable in the development of pharmaceuticals, particularly in the synthesis of active pharmaceutical ingredients (APIs) that target neurological and inflammatory disorders. Additionally, it serves as a building block in the creation of agrochemicals, contributing to the development of pesticides and herbicides. Its nitrile group allows for further functionalization, making it versatile in the production of complex molecules for research and industrial applications.
