Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in agrochemicals for creating herbicides and insecticides due to its pyridine core, which enhances bioavailability and binding affinity. Also employed in research for modifying bioactive molecules, leveraging the hydroxyl and chloro groups for further functionalization. Its structure supports cross-coupling reactions, making it valuable in medicinal chemistry for generating compound libraries.
