In the intricate world of chemical analysis and laboratory research, precise measurements are paramount. Among the array of indispensable reagents, pH indicators play a crucial role, and Cresol Red stands out for its versatility and distinct color transitions. As a leading manufacturer and supplier of high-quality chemicals in China, understanding the applications and benefits of Cresol Red (CAS 1733-12-6) is key for researchers and procurement managers seeking reliable solutions.

Cresol Red, chemically known as o-Cresolsulfonphthalein, is a triarylmethane dye typically supplied as a brown powder. Its primary utility lies in its function as a pH indicator. It exhibits a clear color change from yellow at lower pH levels to a vibrant red or violet at higher pH levels. Specifically, Cresol Red demonstrates transition intervals that are highly valuable for experimentation: it shifts from orange to yellow between pH 1.8 and 2.0, and more significantly, from yellow to violet across the pH range of 7.0 to 8.8. This makes it an excellent choice for monitoring neutral to slightly alkaline conditions, a common requirement in many chemical processes and biological assays. When you need to buy a reliable pH indicator, sourcing from a reputable China supplier like us ensures consistent performance.

Beyond its role as a pH indicator, Cresol Red has significant applications in biochemistry. It is frequently used in conjunction with lead acetate for the detection of urease activity after polyacrylamide gel electrophoresis (PAGE). This specific application highlights its importance in enzyme activity studies and protein analysis. Furthermore, it serves as a tracking dye in various forms of electrophoresis, including DNA, RNA (agarose), and protein (polyacrylamide) gels. As a tracking dye, it moves through the gel at a predictable rate, allowing researchers to visually monitor the separation process and estimate the migration of their samples. This dual functionality makes Cresol Red a cost-effective and efficient reagent for laboratories.
