Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of nicotinic acid derivatives which are important in treating lipid disorders. It serves as an acylating agent in organic reactions, enabling the introduction of pyridine-based moieties into larger molecules. Commonly applied in the development of agrochemicals and functional materials due to its reactivity and stability in controlled environments. Also utilized in research settings for modifying bioactive compounds and enhancing drug delivery systems. Additionally, it is employed in the manufacture of nicotinamide (vitamin B3), essential for energy metabolism.
