This chemical is primarily utilized in the field of biomedical imaging and diagnostics due to its strong near-infrared (NIR) absorption and fluorescence properties. It is commonly employed as a fluorescent dye in various imaging techniques, such as fluorescence microscopy and in vivo imaging, to visualize and track biological processes at the cellular and molecular levels. Its NIR fluorescence makes it particularly suitable for deep tissue imaging, as it minimizes background interference and allows for clearer visualization of targeted areas. Additionally, it is used in the development of optical sensors and probes for detecting specific biomolecules or environmental conditions in research and clinical settings. Its stability and high sensitivity also make it a valuable tool in photodynamic therapy, where it can be activated by light to produce therapeutic effects.
