Orange G is widely used as a staining agent in biological and histochemical applications. It is particularly effective in staining proteins and nucleic acids, making it valuable for visualizing cellular components under a microscope. In the textile industry, it serves as a dye for coloring fabrics, especially wool and silk, due to its vibrant orange hue. Additionally, it is utilized in paper staining and as an indicator in certain chemical reactions. Its ability to bind selectively to specific materials makes it a versatile tool in both scientific research and industrial processes.
