In the pursuit of scientific precision, advanced chemical analysis relies on high-performance reagents that deliver consistent and accurate results. Cresol Purple, identified by CAS 2303-01-7, is one such indispensable chemical. This sulfonphthalein-based pH indicator is a cornerstone in various analytical techniques, most notably spectrophotometry, where its distinct color transitions are leveraged for quantitative pH determination. As a dedicated manufacturer and supplier based in China, we are proud to offer high-purity Cresol Purple to the global scientific community, empowering researchers and industrial chemists with reliable analytical tools.

Cresol Purple, also known as m-cresol purple, is prized for its utility in measuring pH across a notable range. It exhibits a color change from red to yellow between pH 1.2 and 2.8, and a second transition from yellow to purple between pH 7.4 and 9.0. This characteristic makes it exceptionally useful for applications that require monitoring pH in both acidic and neutral to slightly alkaline environments. When scientists decide to buy Cresol Purple, they are often looking for this specific performance profile to ensure the accuracy of their experimental setups.

The integration of Cresol Purple into spectrophotometric methods is a testament to its analytical power. Spectrophotometers measure how much light a sample absorbs at specific wavelengths. For Cresol Purple, these absorption patterns change predictably with pH. By calibrating the instrument with known standards, researchers can accurately determine the pH of unknown samples by measuring their absorbance in the presence of Cresol Purple. This method is widely adopted in fields such as environmental monitoring, where understanding water pH is critical for ecosystem health, and in quality control within the pharmaceutical and food industries. Procuring this reagent from a trusted Chinese manufacturer ensures that the purity and concentration are precisely controlled, which is vital for validating spectrophotometric readings.

Furthermore, Cresol Purple's role extends to medical applications, serving as a capnographic indicator to confirm proper tracheal intubation by detecting carbon dioxide levels. This dual application underscores its importance not just in chemical laboratories but also in critical care settings. For businesses and research institutions requiring a consistent supply, partnering with a reliable manufacturer and supplier of Cresol Purple from China offers a strategic advantage in terms of cost-effectiveness and logistical efficiency.

For laboratories engaged in sophisticated analytical work, the choice of pH indicator can significantly impact the validity of results.
