Cresol Red Sodium Salt is a sodium salt derivative of Cresol Red, a triphenylmethane dye. Its chemical structure consists of three phenolic groups and a sulfonated phthalide ring, similar to the free acid form of Cresol Red. However, the sodium salt form enhances its solubility in water, making it more convenient for use in aqueous solutions. In acidic solutions, it appears yellow, while in alkaline solutions, it turns red. The transition pH range for Cresol Red Sodium Salt is approximately 7.2 to 8.8. Its chemical formula is C21H17NaO5S. Cresol Red Sodium Salt is a pH indicator commonly used in laboratory settings, particularly in biochemical and biological applications.
