Product Description:
α-Naphtholbenzein is primarily used as a pH indicator in various chemical and biological applications. It is particularly effective in titrations, where it helps to determine the endpoint of acid-base reactions due to its distinct color change at specific pH levels. This compound is also utilized in analytical chemistry for detecting metal ions, as it forms colored complexes with certain metals, aiding in their identification and quantification. Additionally, α-Naphtholbenzein is employed in research laboratories for studying enzyme activity and other biochemical processes that are pH-sensitive. Its ability to provide clear visual cues makes it a valuable tool in both educational and professional settings for experiments requiring precise pH measurements.
