Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) involving pyridine derivatives. It serves as a building block in reactions where the cyano and nitro groups can be selectively modified to introduce amine, carboxylic acid, or heterocyclic functionalities. Commonly applied in the preparation of kinase inhibitors and other bioactive molecules in medicinal chemistry. Also utilized in agrochemical research for developing novel pesticides and herbicides due to its reactivity and structural properties.
