Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. Its structure allows for selective binding in biological systems, making it valuable in creating active pharmaceutical ingredients. Also employed in agrochemicals for the production of herbicides and pesticides due to its reactivity and stability in various chemical pathways. Commonly utilized in cross-coupling reactions, such as Sonogashira coupling, to build complex organic molecules in research and industrial settings.
