Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic acid derivatives with potential therapeutic effects. Commonly employed in the preparation of vasodilators and lipid-lowering agents. Also utilized in research settings for the modification of pyridine-based compounds to enhance bioavailability or alter pharmacokinetic properties. Serves as a building block in the creation of agrochemicals and functional materials due to its reactive ester and acetyl groups.
