Bromoxylenol Blue (also known as Bromothymol Blue) is a widely used pH indicator in laboratory and industrial applications. It exhibits a distinct color change from yellow to blue within the pH range of 6.0 to 7.6, making it ideal for determining the endpoint in acid-base titrations and assessing the acidity or alkalinity of solutions in analytical chemistry. In microbiology, it is commonly incorporated into culture media to detect pH changes resulting from microbial metabolism, aiding in the identification of bacteria. In environmental science, it helps monitor water quality by indicating pH variations in aquatic systems. Its reliability and versatility position it as an essential tool in scientific research, quality control, and biochemical assays.
