Used extensively in the field of photography as a sensitizing dye for silver halide emulsions, enhancing the light absorption properties of photographic films. It plays a crucial role in improving the sensitivity of films to specific wavelengths of light, particularly in the green to red spectrum, which is essential for high-quality color reproduction in photographic images.

In scientific research, it serves as a fluorescent dye for biological staining and imaging. Its ability to bind to specific cellular components makes it valuable for studying cell structures and functions under a microscope. This application is particularly useful in live-cell imaging, where it helps in tracking dynamic processes within cells.

Additionally, it finds use in the development of organic electronic devices, such as organic light-emitting diodes (OLEDs) and organic photovoltaics (OPVs). Its unique electronic properties contribute to the efficient conversion of light into electricity or vice versa, making it a key component in the advancement of sustainable energy technologies.
