Used primarily in biochemical research as a substrate for studying enzyme activity, particularly sulfatases. It helps in understanding the kinetics and mechanisms of enzyme-catalyzed reactions. Additionally, it serves as a tool in diagnostic assays to detect and measure sulfatase activity in various biological samples, aiding in the study of metabolic pathways and enzyme-related disorders. Its application extends to environmental monitoring, where it can be utilized to assess the presence and activity of sulfatase-producing microorganisms in soil and water systems.
