Used as a fluorescent probe in biochemical and biophysical research due to its strong fluorescence properties. It labels proteins, lipids, and membranes to study molecular interactions, dynamics, and conformational changes. Commonly employed in fluorescence spectroscopy, energy transfer studies (FRET), and imaging to monitor cellular processes. Its long hydrophobic linker allows for effective incorporation into lipid bilayers, making it useful in membrane fluidity and fusion experiments. Also utilized in the development of biosensors and diagnostic assays where sensitive detection of molecular events is required.
