Used as a key intermediate in the synthesis of fluorinated pyridine-based pharmaceuticals, particularly in the development of kinase inhibitors and antiviral agents. Its ethynyl and fluoro functional groups enable selective cross-coupling reactions, making it valuable in medicinal chemistry for building complex drug molecules. The acetate group acts as a protecting group, allowing controlled deprotection during multi-step syntheses. Commonly employed in research settings for designing bioactive compounds with enhanced metabolic stability and target specificity.
