Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly for targeting cancer-related enzymes and receptors involved in chronic diseases such as cancer and inflammation. The ethynyl (alkyne) group in its structure enables strong binding interactions with biological targets and facilitates click chemistry reactions to generate diverse derivatives for biological screening. This makes it valuable in developing anti-tumor agents and lead compounds for novel drug design. Also explored in agrochemicals for creating novel pesticides due to its reactivity and stability in functional molecule design. Commonly employed in medicinal chemistry for scaffold modification to enhance drug potency and selectivity.
