Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its alkyne and hydroxyl functional groups allow for further chemical modifications through click chemistry and esterification, making it valuable in medicinal chemistry for building complex drug-like molecules. Also employed in the preparation of pyridine-based derivatives that exhibit biological activity, including anti-inflammatory and antiviral properties. Its benzyl-protected hydroxyl group enables selective deprotection under mild conditions, facilitating stepwise synthesis in drug discovery research.
