6-((tert-Butoxycarbonyl)amino)nicotinic acid is primarily used in organic synthesis as a building block for the preparation of more complex molecules. It is often employed in peptide synthesis, where the tert-butoxycarbonyl (Boc) group serves as a protective group for amines, preventing unwanted reactions during the synthesis process. This compound is also utilized in the development of pharmaceuticals, particularly in the creation of active pharmaceutical ingredients (APIs) that require nicotinic acid derivatives. Additionally, it finds application in the synthesis of agrochemicals and other fine chemicals, where its structural features contribute to the desired properties of the final product. Its versatility in protecting and modifying functional groups makes it a valuable reagent in various chemical research and industrial applications.
