Used as a fluorescent probe in biochemical and biophysical research to study protein conformation and interactions. It binds to hydrophobic regions of proteins, allowing visualization and analysis of structural changes. Commonly applied in fluorescence spectroscopy and microscopy to monitor protein folding, aggregation, and binding events. Also utilized in environmental studies to detect and quantify pollutants by measuring fluorescence changes in response to specific analytes. Its sensitivity to environmental conditions makes it valuable for studying membrane dynamics and lipid-protein interactions.
