While most commonly recognized for its role as an acid-base indicator in titrations, Bromophenol Blue (CAS 115-39-9) possesses a versatility that extends into various facets of chemical research and industrial applications. Its distinct color transitions, particularly its shift from yellow to blue-purple between pH 3.0 and 4.6, make it a valuable tool in scenarios where pH monitoring is critical but perhaps not in the context of a standard volumetric analysis.

Beyond its well-established use in determining the endpoint of acid-base reactions, Bromophenol Blue finds applications in biological staining and as a marker in electrophoresis. In molecular biology, it is sometimes used as a tracking dye in gel electrophoresis to visually monitor the progress of DNA or RNA migration through the gel. Its relative inertness and visible color change under specific conditions make it a practical choice for these purposes. For researchers in these fields, sourcing high-purity Bromophenol Blue from a reliable manufacturer is essential to ensure accurate and observable results. Many suppliers offer samples, allowing scientists to test its suitability for their specific experimental protocols.

Furthermore, Bromophenol Blue can be incorporated into formulations for various industrial processes where pH needs to be monitored or maintained within a certain range. Its availability as a light red powder with a high assay (e.g., 99%) from reputable China-based manufacturers makes it an accessible reagent for a broad spectrum of scientific and technical applications. When considering your next purchase, think about how this adaptable indicator might enhance your research or industrial processes. Don't hesitate to request a quote from a trusted supplier to explore buying options for your specific laboratory or industrial needs.
