Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) containing pyridine rings. Its reactivity allows for efficient acylation of amines and alcohols, making it valuable in creating amide and ester bonds common in drug molecules. Commonly employed in the production of agrochemicals and specialty chemicals where fluorinated pyridine derivatives enhance biological activity or metabolic stability. Also utilized in research settings for the preparation of novel heterocyclic compounds with potential therapeutic applications.
