Used in biochemical research as an intermediate in the hexosamine biosynthesis pathway, particularly in studies related to glycosylation and insulin resistance. Serves as a substrate in enzyme assays involving phosphoacetylglucosamine mutase and other metabolic enzymes. Also utilized in cell culture applications where modulation of glycan synthesis is required. Its disodium salt form enhances solubility and stability in aqueous solutions, making it suitable for in vitro studies.
