This chemical is widely used as a pH indicator due to its ability to change color in response to varying pH levels. It is particularly effective in the pH range of 3.0 to 4.6, transitioning from yellow to red, making it suitable for titrations and laboratory experiments requiring precise pH measurements. Additionally, it is utilized in dyeing processes for textiles, where it imparts vibrant colors and demonstrates good stability under different conditions. Its properties also make it valuable in biochemical research for staining and detecting specific cellular components. Furthermore, it finds application in the production of inks and coatings, where its color-changing ability is leveraged for visual indicators in smart materials.
