Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of kinase inhibitors for cancer treatment. Its structure allows for selective binding and modification in drug design, enhancing potency and specificity. Commonly employed in organic synthesis to introduce pyridinyl and alkyne functionalities, facilitating cross-coupling reactions such as Sonogashira coupling. Also utilized in the preparation of bioactive molecules and agrochemicals due to its reactivity and functional group compatibility.
