Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) with biological activity. It serves as a building block in the preparation of heterocyclic compounds that exhibit antimicrobial, antiviral, or anticancer properties. Its nitrile and chlorine functionalities allow for further chemical modifications, enabling the introduction of various substituents to tailor molecular structure for drug design. Also employed in agrochemical research for developing novel pesticides and herbicides due to its reactivity and ability to form stable derivatives.
