Tetrabromophenolphthalein ethyl ester, also known as Bromophenol Blue, is a pH indicator commonly used in biochemistry and analytical chemistry. Its synthesis involves the bromination of phenolphthalein followed by esterification with ethanol. Bromophenol Blue exhibits a color change from yellow in acidic solutions to blue in basic solutions, making it useful for determining the pH of solutions. The compound is widely studied for its ability to bind to proteins, making it a valuable tool for studying protein structure and function. Its unique spectroscopic properties also make it a useful reagent in various analytical techniques, including electrophoresis and spectrophotometry.'
