Used as a fluorescent probe in biochemical analysis, particularly for tracking proteins or nucleic acids in biological systems. It fluoresces when excited by specific wavelength light, enabling efficient use as a tracker. Additionally, it is applied in research on cell membrane mechanisms and substance transport across membranes, as it can insert into membrane structures to facilitate detailed studies of membrane behavior. Its strong fluorescence allows sensitive detection at low concentrations and it is stable under a range of pH conditions, making it suitable for diverse laboratory applications.
