Titration is a cornerstone of quantitative chemical analysis, and the choice of indicator is paramount to achieving accurate results.

O-Cresolphthalein, a widely recognized chemical indicator, offers a precise solution for specific titration needs. As a trusted manufacturer in China, we understand the importance of reliable reagents. This organic intermediate, known by its CAS number 596-27-0, is specifically designed to provide clear visual endpoints in the pH range of 8.2 to 9.8, making it indispensable for certain analytical procedures.

The primary function of O-Cresolphthalein is to signal the completion of a chemical reaction during titration through a distinct color change. In its acidic form, it appears colorless, but as the solution becomes more alkaline, specifically above pH 8.2, it transitions to a vibrant red. This color shift is crucial for identifying the equivalence point, especially in titrations involving substances where the expected pH at equivalence falls within this alkaline spectrum. Many laboratories actively seek to buy O-Cresolphthalein for its predictable behavior.

The benefits of using O-Cresolphthalein as a chemical indicator for titration are numerous. Its sharp color change minimizes ambiguity, leading to more precise measurements and reliable data. For laboratories focused on quality and accuracy, purchasing O-Cresolphthalein from a reputable supplier in China guarantees a product that meets stringent quality standards. This ensures consistent performance across experiments, whether you are performing routine analyses or in-depth research.

When considering where to buy O-Cresolphthalein, partnering with a manufacturer that emphasizes quality control is key. A dependable supplier will not only provide the chemical itself but also offer support and expertise to ensure you can leverage its full potential. Make O-Cresolphthalein your go-to indicator for accurate and efficient titration processes.
