This chemical is primarily used as a fluorescent dye in various scientific and medical applications. Its ability to absorb and emit light in the near-infrared region makes it valuable for biological imaging, particularly in studying cellular processes and molecular interactions. It is often employed in fluorescence microscopy to visualize and track specific structures or molecules within cells. Additionally, it is utilized in photodynamic therapy, where it helps in targeting and destroying cancer cells by generating reactive oxygen species upon light activation. Its stability and optical properties also make it suitable for use in optical sensors and as a probe in biochemical research.
