Cresol red is a pH indicator dye that is commonly used in chemical and biological research. It is synthesized from the condensation of 3,3'-dimethyl-4,4'-dihydroxyfuchsone and m-cresol. The molecule exhibits a distinct color change over a pH range of 0.2-2.8 (red) and 7.2-8.8 (yellow). Its color change is reversible and can be used to determine the pH of solutions. Cresol red is widely used in applications such as:
- pH determination in biological assays, such as enzyme activity and protein assays.
- as an indicator in acid-base titrations.
- as a staining agent in histology and cytology, particularly in staining mitochondria and Golgi apparatus.
- as a component of chemical sensors, such as those used to monitor water quality.
- as a model system for understanding the structure-color relationship of pH indicators.
Research on cresol red focuses on its application in various scientific fields, including biochemistry, analytical chemistry, and materials science. It is studied to understand its chemical properties, develop new applications, and improve existing methods using this versatile compound.'
