In the complex world of chemical synthesis and laboratory analysis, specific compounds serve as critical tools for observation and measurement. Tetrabromophenol Blue, with its distinctive identification number CAS 4430-25-5, is one such compound. As a sulfonphthalein dye, it functions primarily as a pH indicator, a role that is indispensable in numerous scientific applications. NINGBO INNO PHARMCHEM CO.,LTD. is a key supplier of this important chemical, ensuring researchers have access to reliable analytical reagents.

The intrinsic tetrabromophenol blue properties dictate its utility. Typically appearing as a yellowish or brown powder, its most notable characteristic is its color change in response to pH variations. It transitions from a yellow hue in acidic environments to a distinct blue color in basic environments, with the critical transition occurring within the pH range of 3.0 to 4.6. This well-defined tetrabromophenol blue pH range makes it ideal for applications requiring precise pH monitoring, such as acid-base titrations where identifying the exact endpoint is crucial for accurate results. The clarity of this color change is a significant advantage.

Beyond its primary function as a pH indicator, Tetrabromophenol Blue has expanded applications in various scientific fields. It is widely used as a tracking dye in gel electrophoresis, providing a visual marker to monitor the movement and separation of nucleic acids or proteins. This application relies on the dye's ability to migrate through the gel matrix, offering a visual confirmation of the electrophoresis process. Additionally, it is sometimes incorporated into protocols for virus testing, demonstrating its versatility in biological research.

For researchers and institutions, knowing where to buy tetrabromophenol blue is essential for maintaining experimental workflows.
