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 medicinal chemistry. Also employed in agrochemicals to enhance the efficacy of crop protection agents. The trifluoromethyl group improves metabolic stability, while the ethynyl moiety enables further functionalization through coupling reactions. Widely utilized in research for building complex heterocyclic compounds.
