Phenol red, a red powder. In biochemical experiments, it is often used as a pH indicator, and its color changes with the pH value of the solution, appearing yellow in acidic environments and red in alkaline environments, thus helping to accurately determine the acidity or alkalinity of the solution. In cell culture, it can be used to monitor changes in the pH of the culture medium. In pharmacological research, it is sometimes used to evaluate the effects of drugs on acid-base balance. Phenol red is usually produced through specific chemical synthesis processes and has important practical value in multiple research fields such as chemistry and biology.
