Product Description:
Bromophenol blue is widely used as a pH indicator in various laboratory applications. It is particularly useful in titration experiments, where it helps determine the endpoint of acid-base reactions by changing color at a specific pH range, typically between 3.0 (yellow) and 4.6 (blue). In biochemistry, it is often employed in gel electrophoresis as a tracking dye to monitor the progress of DNA, RNA, or protein migration. Additionally, it is used in microbiology for staining and visualizing bacterial colonies. Its vibrant color change makes it a valuable tool in educational settings for teaching pH concepts and chemical reactions.
