Used primarily as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other biologically active compounds. Its structure supports the construction of complex heterocyclic systems found in drug candidates targeting cancer and inflammatory diseases. The nitrile and chloro functional groups allow for further chemical modifications, enabling the introduction of various substituents to fine-tune biological activity. Also employed in agrochemical research for designing new pesticides due to its ability to interact with specific enzymatic pathways in pests. Its aromatic and heterocyclic nature enhances binding affinity in receptor sites, making it valuable in medicinal chemistry for lead optimization.
