Analytical chemistry relies on precise measurements and clear indicators to unravel the composition and properties of substances. Bromophenol Blue Sodium Salt (CAS 34725-61-6) stands out as a fundamental reagent, primarily valued for its role as a pH indicator. Its reliable color transitions across a specific pH range make it indispensable for various analytical procedures, from simple titrations to more complex qualitative tests. As a dedicated chemical supplier, we provide high-purity Bromophenol Blue Sodium Salt to empower analytical chemists in their pursuit of accurate results.

The utility of Bromophenol Blue Sodium Salt in analytical chemistry is deeply rooted in its behavior as a sulfonphthalein dye. Its molecular structure undergoes a significant change in conjugation system upon alteration of the surrounding pH. Specifically, it exhibits a yellow color in solutions with a pH below 3.0, transitioning to a blue hue as the pH rises above 4.6. The intermediate range (pH 3.0-4.6) often shows a green or purplish color, depending on the exact pH and concentration. This predictable and visible color change serves as a vital endpoint indicator in acid-base titrations. When performing titrations, the ability to accurately pinpoint the equivalence point is crucial for determining unknown concentrations or verifying the purity of substances. Therefore, sourcing a consistent and high-quality Bromophenol Blue Sodium Salt from a reliable manufacturer is paramount for reproducible analytical outcomes.

Beyond its use in titrimetry, Bromophenol Blue Sodium Salt can also be employed in other analytical applications where pH monitoring is necessary. For instance, in certain enzymatic assays or buffer preparation protocols, maintaining a specific pH is critical for optimal reaction rates or stability. The visual indication provided by Bromophenol Blue can offer a quick and easy method for approximate pH adjustments, complementing more precise electrochemical methods. Laboratories engaged in quality control or research often need to buy this reagent in sufficient quantities to support their ongoing analytical demands. Investigating suppliers that offer competitive pricing for bulk orders can lead to significant cost savings for analytical departments.

The selection of a chemical supplier for analytical reagents like Bromophenol Blue Sodium Salt should be based on a combination of factors, including product purity, consistency, availability, and customer support. Manufacturers who adhere to strict quality control standards and provide detailed documentation, such as Certificates of Analysis, are preferred. These documents typically outline the specifications met by the batch, confirming its suitability for analytical applications. For any laboratory focused on accurate and reliable chemical analysis, ensuring a steady supply of high-quality Bromophenol Blue Sodium Salt is a strategic imperative. We encourage professionals to explore our offerings and experience the difference that quality reagents make in analytical chemistry.
