Bromochlorophenol Blue Sodium Salt

Description:
Bromochlorophenol Blue Sodium Salt is a synthetic dye commonly used as a pH indicator in various biochemical and analytical applications. It exhibits a distinct color change in response to pH variations, typically transitioning from yellow in acidic conditions to blue in alkaline environments. This compound is characterized by its solubility in water, making it suitable for use in aqueous solutions. Its molecular structure includes bromine and chlorine substituents on a phenolic ring, contributing to its unique colorimetric properties. The sodium salt form enhances its solubility and stability in solution. In laboratory settings, Bromochlorophenol Blue is often employed in electrophoresis as a tracking dye, allowing researchers to monitor the progress of sample migration. Additionally, it is utilized in various titrations and as a staining agent in microbiological studies. Safety data indicates that while it is generally considered low in toxicity, appropriate handling and disposal measures should be observed to minimize environmental impact.
