Cresol Red, a well-established acid-base indicator with CAS number 1733-12-6, plays a pivotal role in numerous chemical applications. Its reliable performance as a pH indicator, characterized by distinct color changes, makes it an indispensable reagent in laboratories and industrial settings worldwide. As a prominent chemical manufacturer based in China, we supply high-quality Cresol Red tailored to meet the diverse needs of researchers and procurement specialists.

One of the primary applications of Cresol Red is in acid-base titrations. Its transition range, typically from yellow at lower pH values to purple at higher pH values (around pH 7.2-8.8), allows for precise endpoint determination in neutralization reactions. This precision is vital for quality control in manufacturing processes and for accurate experimental outcomes in research laboratories. When you purchase Cresol Red, you're acquiring a tool that enhances the accuracy of your chemical analyses.

Beyond titrations, Cresol Red finds application in biological sciences. It is used as a stain, often in conjunction with lead acetate, for the detection of urease activity in techniques like PAGE (Polyacrylamide Gel Electrophoresis). This application highlights its utility in biochemical research and diagnostics. Furthermore, it serves as a tracking dye in electrophoresis gels for DNA, RNA, and protein analysis, helping to visualize the migration of molecules and monitor the progress of separation.

The chemical industry also leverages Cresol Red in various monitoring systems, including combustion gas detection and optical sensors, where its colorimetric properties are exploited for real-time analysis. For businesses seeking a reliable source for this versatile indicator, partnering with an established manufacturer and supplier like ourselves ensures access to a high-purity product at a competitive price. We are committed to providing the analytical and industrial sectors with dependable chemical reagents that drive scientific advancement and operational efficiency.
