The world of chemistry is filled with compounds that perform specific, often visually striking, functions. Tetrabromophenol Blue, known scientifically by its CAS number 4430-25-5, is a prime example of such a compound, serving as a pivotal pH indicator. Its ability to change color based on the acidity or alkalinity of a solution makes it an indispensable tool in laboratories worldwide. NINGBO INNO PHARMCHEM CO.,LTD. is committed to supplying this and other vital reagents to the scientific community.

The core function of Tetrabromophenol Blue revolves around its predictable color transitions. In acidic conditions, typically below pH 3.0, it exhibits a yellow color. As the pH increases, it undergoes a transition, shifting to blue around pH 4.6. This specific tetrabromophenol blue pH range is critical for its application in acid-base titrations, where it signals the precise moment a reaction reaches completion. The clarity of this color change from yellow to blue provides scientists with a reliable visual endpoint.

Beyond its primary use in titrations, Tetrabromophenol Blue has carved out significant roles in other scientific domains. In molecular biology, it functions as a tracking dye in gel electrophoresis. When added to DNA or protein samples, it moves through the gel along with the molecules, allowing researchers to monitor the progress of the separation process and estimate migration distances. This visual aid simplifies experimental procedures and enhances accuracy. Furthermore, it is sometimes employed in specific methods for virus testing, showcasing its broad applicability.

For researchers seeking to incorporate Tetrabromophenol Blue into their work, understanding where to buy tetrabromophenol blue is paramount.
