Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in medicinal chemistry due to its ability to participate in cross-coupling reactions and nucleophilic substitutions, enabling the construction of complex heterocyclic systems. Its nitrile and chloro functionalities allow for selective modifications, making it valuable in optimizing drug candidates for improved potency and selectivity. Also employed in agrochemical research for designing novel bioactive molecules with potential pesticidal or herbicidal activity.
