Chrysoidin is primarily used as a dye in various industries, particularly in textile and leather manufacturing, where it imparts a vibrant orange to red color to fabrics and materials. It is also employed in biological staining, aiding in the visualization of microscopic structures in laboratory settings. Additionally, chrysoidin has been utilized in the production of inks and paper coatings, enhancing the visual appeal of printed materials. In some cases, it serves as an intermediate in the synthesis of other chemical compounds. However, its use has declined in certain applications due to safety and environmental concerns.
