Bromophenol blue CAS:115-39-9 Manufacturer Price

Bromophenol blue is a pH indicator that changes color depending on the acidity or alkalinity of a solution. In its acidic form, it appears yellow, while in its basic form, it turns blue. This makes it useful for visually determining the pH of a solution, especially in laboratory settings. Additionally, it is commonly used in gel electrophoresis to track the movement of DNA and RNA molecules. Its color change helps researchers visualize the progress of the separation process.
