Used as a red dye in various industries, including food, cosmetics, and textiles, to provide vibrant coloration. In microbiology, it serves as a staining agent to differentiate bacterial colonies. Additionally, it is employed in dental disclosing tablets to highlight plaque on teeth for oral hygiene purposes. In analytical chemistry, it acts as a pH indicator due to its color-changing properties in different pH environments. Its fluorescent nature also makes it useful in certain biomedical research applications, such as tracking cellular processes.
