D-Hamamelose is primarily used in research and development within the fields of biochemistry and organic chemistry. It serves as a valuable compound for studying carbohydrate metabolism and enzyme mechanisms due to its unique structure. In pharmaceutical research, it is explored for its potential role in drug delivery systems, particularly in the design of glycosylated drugs that can improve solubility and bioavailability. Additionally, D-Hamamelose is of interest in the development of natural sweeteners and functional foods, as it may offer alternative sugar properties with reduced caloric impact. Its applications also extend to cosmetic formulations, where it is investigated for its moisturizing and skin-soothing properties.
