This compound is primarily used in the synthesis of complex carbohydrates and glycoconjugates, which are essential in biochemical research and drug development. It serves as a key intermediate in the preparation of modified sugars, enabling the study of carbohydrate-protein interactions. These interactions are crucial for understanding cellular communication, immune responses, and pathogen recognition. Additionally, its ethynyl group allows for further functionalization through click chemistry, making it valuable in the development of targeted therapies and diagnostic tools. Its application extends to the production of glycoconjugate vaccines, where it aids in enhancing immune responses against specific pathogens.
