In the realm of chemical analysis, precision and reliability are non-negotiable. Cresol Purple (CAS 2303-01-7) stands as a key reagent, widely recognized for its efficacy as a pH indicator. Its distinct colorimetric properties make it invaluable in spectrophotometric applications and other critical analytical tasks. As a prominent manufacturer and supplier in China, we are committed to providing the scientific community with high-quality Cresol Purple, ensuring that your analytical endeavors are supported by dependable reagents.

Cresol Purple, also known as m-cresol purple, is a synthetic organic compound belonging to the sulfonphthalein family of dyes. Its primary function is as a pH indicator, signaling changes in acidity or alkalinity through visible color shifts. The compound exhibits two significant transition ranges: it shifts from red to yellow between pH 1.2 and 2.8, and from yellow to purple between pH 7.4 and 9.0. This dual functionality allows for precise pH monitoring across a moderately wide spectrum, making it a versatile choice for many laboratory protocols. For researchers looking to buy Cresol Purple, these properties are central to its selection.

The application of Cresol Purple in spectrophotometry is particularly noteworthy. Spectrophotometric pH measurement relies on the principle that the absorption of light by a solution changes with pH when a suitable indicator is present. Cresol Purple's ability to change color in response to pH variations directly translates into measurable changes in light absorbance. This makes it an ideal indicator for quantitative pH analysis in diverse settings, including environmental water testing, industrial process control, and biochemical research. Sourcing high-purity Cresol Purple from a reliable Chinese manufacturer ensures that the indicator's spectral properties are consistent, which is essential for accurate spectrophotometric readings.

Beyond its analytical applications, Cresol Purple also serves a critical role in medical diagnostics, specifically as a capnographic indicator used to detect end-tidal carbon dioxide, confirming correct tracheal intubation. This medical application underscores the compound's importance in ensuring patient safety.
