In the intricate ecosystem of a research laboratory, certain chemicals serve as indispensable workhorses, facilitating a vast array of experimental procedures. Bromophenol Blue (BPB) stands out among these essential laboratory chemicals due to its versatility and reliability. This article offers an in-depth look at Bromophenol Blue, covering its primary functions as a pH indicator and an electrophoresis tracking dye, and its overall significance in scientific research. NINGBO INNO PHARMCHEM CO.,LTD. is a trusted supplier of this vital compound.

At its core, Bromophenol Blue is renowned for its capabilities as a pH indicator. Its characteristic color change, from yellow at low pH (below 3.0) to blue at higher pH (above 4.6), provides a clear and immediate visual cue for the acidity or alkalinity of a solution. This makes it incredibly useful in titration experiments, where pinpointing the exact moment of an acid-base reaction's completion is critical. The predictability of the bromophenol blue pH indicator range ensures that researchers can depend on it for accurate results in a variety of analytical procedures.

Furthermore, Bromophenol Blue is a critical component in the toolkit for gel electrophoresis. In this technique, which separates biomolecules like DNA, RNA, and proteins based on size and electrical charge, visual markers are essential. Bromophenol Blue, when added to the sample buffer, migrates through the gel, providing a visible front that allows researchers to monitor the progress of the separation. This is particularly important for determining the optimal time to terminate the electrophoresis, preventing samples from migrating off the gel and ensuring effective separation. The ability to buy Bromophenol Blue online from a variety of sources makes it readily accessible for laboratories globally.

The chemical properties of Bromophenol Blue, including its molecular formula (C19H10Br4O5S) and CAS number (115-39-9), are well-documented, ensuring researchers can identify and utilize the correct compound. Its solubility in water and common organic solvents, along with its relative stability, contribute to its ease of handling and preparation for various experimental setups. The uses of Bromophenol Blue are extensive, ranging from educational demonstrations of pH changes to advanced research applications in molecular biology and biochemistry.
