Bromocresol green is widely used as a pH indicator in various laboratory and industrial applications. It is particularly useful in titrations to determine the endpoint of acid-base reactions, as it transitions from yellow in acidic conditions (pH 3.8) to blue in alkaline conditions (pH 5.4). This makes it a valuable tool in analytical chemistry for monitoring pH changes in solutions. Additionally, it is employed in microbiological media to detect pH shifts caused by microbial growth, aiding in the identification and study of microorganisms. In clinical settings, bromocresol green is used in certain diagnostic tests, such as measuring albumin levels in blood serum, where it binds to albumin and produces a color change for quantification. Its versatility and reliability make it a staple in both research and diagnostic laboratories.
