This chemical is primarily utilized in the synthesis of complex carbohydrates and glycoconjugates, which are essential in biochemical and pharmaceutical research. It serves as a key intermediate in the preparation of sialic acid derivatives, which play a critical role in understanding cell communication, immune response, and pathogen interactions. Its application extends to the development of glycoprotein-based drugs and vaccines, particularly in targeting diseases influenced by sialic acid-mediated processes, such as influenza and certain cancers. Additionally, it is used in glycobiology studies to explore the structural and functional roles of carbohydrates in biological systems.
