Bromophenol Blue CAS 115-39-9

1. Bromophenol Blue CAS 115-39-9 is primarily used as a pH indicator in laboratory settings, exhibiting a color change from yellow below pH 3.0 to blue/purple above pH 4.6 .
2. Bromophenol Blue serves as a tracking dye in protein and nucleic acid electrophoresis (agarose and polyacrylamide gels), allowing researchers to monitor the progress of sample migration during separation .
3. Bromophenol Blue is employed as a biological stain and in certain diagnostic tests, including those for assessing liver function, and has been utilized as an industrial dye for coloring fabrics .
4. Researchers also use Bromophenol Blue in environmental monitoring to assess water quality, leveraging its sensitivity to pH changes in aquatic ecosystems .

1. Bromophenol Blue CAS 115-39-9 must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment at room temperature (RT); the powder is stable indefinitely when stored properly .
2. Bromophenol Blue is considered nonhazardous according to GHS classifications for the Hazard Communication Standard, though prudent laboratory practices should always be observed .
3. Personnel should wear chemical-resistant gloves, safety goggles with side-shields, and protective clothing when handling Bromophenol Blue, as it may cause skin, eye, and respiratory tract irritation and will stain skin and clothing .
4. Keep away from incompatible materials such as strong oxidizing agents; avoid formation of dust and aerosols, and wash thoroughly after handling.

1. Isolate the spill area, ensure adequate ventilation, and wear full personal protective equipment including chemical-resistant gloves, safety goggles, and suitable dust respirator when Bromophenol Blue CAS 115-39-9 is released .
2. Sweep up Bromophenol Blue without creating dust using non-sparking tools, and place into a sealed bag or suitable closed container for disposal .
3. Avoid creating dust clouds during cleanup to prevent respiratory exposure; ventilate the area and wash the spill site after material pickup is complete .
4. Dispose of collected material according to local, state, and federal environmental regulations; consult Flinn Suggested Disposal Method #26a or equivalent for guidance.

1. Bromophenol Blue CAS 115-39-9 is classified as nonflammable and noncombustible as a solid; however, when heated to decomposition, it may emit toxic fumes.
2. Use dry chemical powder (tri-class dry chemical extinguisher), carbon dioxide, water spray, or alcohol-resistant foam to extinguish fires involving the product .
3. Firefighters Bromophenol Blue should wear self-contained breathing apparatus in pressure-demand, MSHA/NIOSH approved, and full protective gear when handling burning Bromophenol Blue due to hazardous decomposition gases generated by thermal decomposition .
4. During combustion, may emit irritant and toxic fumes; move containers from the fire area if safe to do so, and contain fire runoff to prevent environmental contamination .
