The efficacy of any chemical reagent hinges on its inherent properties and consistent quality. Tetrabromophenol Blue (CAS 4430-25-5) is no exception. As a key pH indicator and analytical tool, its performance is directly linked to its precise chemical and physical characteristics. At NINGBO INNO PHARMCHEM CO.,LTD., a leading manufacturer in China, we place a strong emphasis on detailing these properties to ensure our clients understand the value and reliability of the Tetrabromophenol Blue they purchase.

Key Chemical and Physical Properties

The primary characteristic that defines Tetrabromophenol Blue's utility is its behavior as a pH indicator. Its molecular structure allows it to exhibit distinct color changes across a specific pH range:

• Appearance: Typically presented as a beige or yellowish-brown powder, its physical form is stable under recommended storage conditions.
• Purity: High purity is critical for accurate analytical results. Our Tetrabromophenol Blue is supplied with an assay of ≥99.0%, minimizing interference from impurities and ensuring consistent performance.
• pH Transition Range: The compound undergoes a noticeable color change from yellow to blue as the pH shifts from approximately 2.8 to 4.6. This defined range is crucial for precise endpoint detection in titrations and for monitoring buffer systems.
• Solubility: While specific solubility varies with the solvent, its compatibility with common laboratory solvents allows for easy preparation of indicator solutions.

Significance of Properties in Applications

These properties directly translate into the reliable performance of Tetrabromophenol Blue in various applications:

• Accurate Titrations: The sharp color change within its pH range makes it an excellent choice for acid-base titrations, providing clear visual confirmation of the equivalence point.
• Electrophoresis: Its migration behavior in gels, combined with its color, allows researchers to track sample movement and the overall progress of electrophoresis runs.
• Diagnostic Kits: When incorporated into diagnostic tools, its predictable color changes can indicate specific conditions or the presence of certain analytes, contributing to diagnostic accuracy.
