Bromophenol blue solution (0.04 wt. % in H2O) is widely utilized in research focused on:

• pH Indicator: Commonly used in laboratories to indicate pH changes in solutions, making it essential for titrations and other chemical analyses.
• Electrophoresis: Serves as a tracking dye in gel electrophoresis, helping researchers visualize the progress of DNA or protein separation during experiments.
• Biological Staining: Utilized in histology and microbiology for staining tissues and cells, aiding in the identification of cellular structures under a microscope.
• Environmental Testing: Applied in water quality testing to detect acidity levels, which is crucial for monitoring aquatic ecosystems and ensuring compliance with environmental regulations.
• Food Industry: Used as a color indicator in food testing to assess pH levels, ensuring product safety and quality during production processes.
