In the precise world of analytical chemistry and laboratory research, accurate pH measurement is paramount. Whether conducting titrations, monitoring reaction conditions, or ensuring product quality, selecting the correct acid-base indicator can make all the difference. As a leading manufacturer and supplier of high-quality laboratory chemicals, we understand the nuances of these essential reagents.

Among the most versatile and widely used indicators is Bromophenol Blue (CAS 115-39-9). This synthetic dye is renowned for its distinct color transition, shifting from yellow at pH 3.0 to blue at pH 4.6. This clear, reversible change makes it an excellent choice for titrations involving strong acids and weak bases, or when monitoring solutions within this specific pH range. For professionals seeking to buy Bromophenol Blue, understanding its optimal application ensures efficient and accurate experimental outcomes. Many labs rely on us as their trusted Bromophenol Blue supplier in China for consistent purity.

When choosing an acid-base indicator, several factors come into play. Firstly, consider the expected pH at the equivalence point of your titration. If you're titrating a strong acid with a strong base, an indicator like Bromothymol Blue (pH 6.0-7.6) might be appropriate, as the equivalence point is typically at pH 7. However, for titrations where the equivalence point falls within the 3.0-4.6 range, Bromophenol Blue is an ideal choice. Its predictable behavior means you can confidently purchase Bromophenol Blue for your specific analytical needs. We often receive inquiries about Bromophenol Blue price, reflecting its demand as a cost-effective yet reliable indicator.

Beyond titrations, Bromophenol Blue also finds critical application as an electrophoresis tracking dye. In molecular biology labs, it’s used to visually monitor the progress of DNA or protein separation in gels. Its migration rate provides a visual cue, allowing researchers to stop the electrophoresis at the optimal time. This dual functionality underscores why many labs choose to buy Bromophenol Blue from reputable manufacturers like us. Ensuring the quality of your electrophoresis dye is as important as the purity of your reagents; that’s why we focus on providing high-grade products.
