Bromocresol Purple, in its sodium salt form (CAS 62625-30-3), is a well-established chemical reagent celebrated for its utility as a pH indicator. Its scientific foundation lies in its molecular structure as a sulfonphthalein dye, which allows it to undergo a distinct visual transformation based on hydrogen ion concentration. This property makes it an indispensable tool in various scientific disciplines, from routine laboratory analysis to specialized biochemical applications.

The core scientific principle behind Bromocresol Purple's function is its behavior as a weak acid that ionizes reversibly in water. As the pH of the solution changes, the dye molecule accepts or releases protons, leading to a change in its electronic structure and, consequently, its color. Specifically, it transitions from yellow at pH values below 5.2 to purple at pH values above 6.8, with intermediate shades in between. This clearly defined transition range is the basis for its widespread use in titrations.

In analytical chemistry, the ability to accurately determine the endpoint of a titration is paramount. When used as a titrant indicator, Bromocresol Purple sodium salt provides a sharp, easily discernible color change that signals the completion of the reaction. This makes it a preferred choice for many acid-base titrations, ensuring precision in quantitative analysis. For laboratories that regularly perform such analyses, sourcing this reagent from a reliable supplier of Bromocresol Purple is crucial.

Beyond traditional chemistry, Bromocresol Purple sodium salt has found significant application in biochemistry and clinical diagnostics. Its use in the spectrophotometric determination of serum albumin is a testament to its sensitivity and reliability. Albumin levels are critical indicators of liver and kidney function, making accurate measurement essential in healthcare settings. When you buy Bromocresol Purple sodium salt for these purposes, you are investing in a reagent that supports vital diagnostic processes.
