Understanding and accurately measuring pH is fundamental across a vast spectrum of scientific disciplines, from environmental monitoring and chemical manufacturing to pharmaceutical research and clinical diagnostics. Among the array of tools available to scientists, pH indicators play a crucial role, providing visual cues for the acidity or alkalinity of a solution. One such indispensable indicator is Cresol Purple, known scientifically by its CAS number 2303-01-7. As a leading supplier in China, we are dedicated to providing researchers and laboratory professionals with high-quality Cresol Purple to ensure the utmost accuracy in their work.

Cresol Purple, also referred to as m-cresol purple or m-cresolsulfonphthalein, is a triphenylmethane dye that exhibits distinct color changes within specific pH ranges. Its utility is particularly pronounced in spectrophotometric pH measurements. Spectrophotometry relies on measuring the absorbance of light by a sample at different wavelengths. For pH indicators like Cresol Purple, this means that as the pH of the solution changes, the indicator molecule alters its structure, leading to a change in its light absorption characteristics. Cresol Purple has two significant pH transition ranges: it changes from red to yellow between pH 1.2 and 2.8, and from yellow to purple between pH 7.4 and 9.0. These well-defined transitions make it an excellent choice for monitoring pH in both acidic and mildly alkaline conditions.

The accuracy provided by Cresol Purple in spectrophotometric analysis is vital for many applications. For instance, in environmental science, precise pH measurements are critical for assessing water quality in rivers, lakes, and oceans. In industrial chemistry, maintaining the correct pH is often key to optimizing reaction yields and product purity. Pharmaceutical companies rely on accurate pH readings for drug formulation, stability testing, and quality control to ensure efficacy and safety. For professionals seeking to buy Cresol Purple, sourcing from a reputable manufacturer in China guarantees access to a product that meets stringent quality standards, essential for reliable analytical outcomes.

Beyond its primary role in pH measurement, Cresol Purple also finds application in medical diagnostics. It is utilized as a capnographic indicator, helping medical professionals detect end-tidal carbon dioxide levels to confirm successful tracheal intubation during emergency procedures. This highlights the versatility and importance of this chemical compound.
