CAS 34725-61-6: Bromophenol blue sodium salt

Description: Bromophenol blue sodium salt is a synthetic dye commonly used as a pH indicator in various biochemical and analytical applications. It appears as a dark blue to purple powder and is soluble in water, exhibiting a color change from yellow at acidic pH levels to blue at alkaline conditions, typically around pH 3.0 to 4.6. This property makes it particularly useful in laboratory settings for monitoring pH changes during titrations or in gel electrophoresis as a tracking dye. The compound has a molecular formula of C19H10Br4O5S and is characterized by its strong absorbance in the visible spectrum, which allows for easy detection. Additionally, bromophenol blue is non-toxic and generally regarded as safe for use in laboratory environments, although proper handling and disposal procedures should always be followed. Its stability under various conditions and ease of use contribute to its popularity in research and educational settings.
