For professionals in analytical chemistry and molecular biology, understanding the properties and applications of key reagents is paramount. Bromophenol Blue (CAS 115-39-9) stands out as a remarkably versatile compound, primarily serving two critical functions: as a reliable pH indicator and an indispensable tracking dye in gel electrophoresis. At NINGBO INNO PHARMCHEM CO.,LTD., we pride ourselves on supplying high-quality Bromophenol Blue to meet the exacting demands of modern laboratories.

As a pH indicator, Bromophenol Blue exhibits a distinct color change within a specific pH range. Typically, it transitions from yellow in acidic conditions (around pH 3.0) to blue in more alkaline conditions (around pH 4.6). This clear, reversible color change makes it an excellent choice for endpoint detection in acid-base titrations, especially those involving strong acids. For researchers looking to buy this vital reagent, understanding its pH transition range is key to its successful application in analytical procedures.

Beyond its role in titration, Bromophenol Blue is a staple in molecular biology laboratories for gel electrophoresis. When loading DNA or protein samples onto an electrophoresis gel, a tracking dye is essential to visually monitor the progress of the separation. Bromophenol Blue, with its relatively small molecular size, migrates through the gel matrix alongside the biomolecules, providing a visual cue for when the run is nearing completion. This allows scientists to stop the electrophoresis at the optimal time, preventing sample diffusion and ensuring clearer results. When sourcing electrophoresis supplies, many researchers specifically seek out high-purity Bromophenol Blue from reputable manufacturers in China.

The demand for Bromophenol Blue continues to grow, driven by its broad utility. Researchers often inquire about the price and availability of this compound, looking for a dependable supplier who can guarantee consistency and purity. NINGBO INNO PHARMCHEM CO.,LTD. serves as a leading manufacturer and supplier, dedicated to providing B2B clients with competitive pricing and a stable supply chain.
