Bromocresol purple is widely used as a pH indicator in various scientific and industrial applications. It is particularly useful in microbiology and biochemistry for monitoring pH changes in cell cultures and enzymatic reactions. The indicator changes color from yellow to purple as the pH shifts from acidic (pH 5.2) to basic (pH 6.8), making it ideal for detecting subtle pH variations in sensitive environments. In clinical laboratories, bromocresol purple is employed in diagnostic tests, such as measuring albumin levels in blood serum. Its ability to form a distinct color complex with albumin allows for accurate quantification, aiding in the diagnosis of liver and kidney diseases. Additionally, it is used in educational settings for teaching acid-base titration experiments, helping students visualize pH transitions during chemical reactions. Its stability and clear color change make it a reliable tool for both research and practical applications.
