Used extensively as a fluorescent tracer in various industries, particularly in environmental studies to track water flow and detect leaks in systems. Its strong fluorescence under UV light makes it valuable in hydrological research for studying groundwater movement and surface water interactions. In the textile industry, it serves as a dyeing auxiliary to enhance color brightness and uniformity. Additionally, it is employed in biological and biochemical research as a fluorescent marker for imaging and detection purposes. Its water-soluble nature and stability under different conditions make it a reliable choice for these applications.
