Used as a fluorogenic substrate in enzymatic assays to detect and quantify the activity of α-glucosidase enzymes. Upon enzymatic hydrolysis, it releases 4-methylumbelliferone, a highly fluorescent compound, allowing sensitive detection even at low enzyme concentrations. Commonly employed in clinical diagnostics, microbiology, and biochemical research to study enzyme kinetics, inhibition, and cellular enzyme expression. Its sulfamino modification enhances stability and specificity toward certain enzyme isoforms. The sodium salt form improves solubility in aqueous assay buffers, making it suitable for high-throughput screening and kinetic studies.
