The accurate determination of pH is fundamental to numerous scientific and industrial processes.

In the realm of analytical chemistry, pH indicators play a pivotal role, acting as visual guides to signal the completion of a reaction or a specific pH threshold. Among these, O-Cresolphthalein stands out as a reliable and effective choice for a particular pH range. This organic compound, often sought after as a high-quality chemical from a trusted supplier in China, is invaluable for researchers and technicians alike.

O-Cresolphthalein, with its CAS number 596-27-0, is known for its distinct color transformation. It exhibits a clear, colorless state at pH 8.2 and gradually turns red as the pH increases to 9.8. This specific transition makes it an excellent indicator for titrations involving weak acids and strong bases, or vice versa, where the equivalence point falls within this alkaline range. When you decide to purchase O-Cresolphthalein, you are investing in precision for your laboratory work.

Utilizing O-Cresolphthalein in your experiments is straightforward. Typically, a small amount of the indicator is added to the analyte solution. As the titrant is added, the solution's pH changes. The first persistent appearance of a pink or red hue signals the endpoint of the titration. This visual cue is critical for accurate data collection, ensuring that your scientific conclusions are based on reliable measurements. Many laboratories choose to buy O-Cresolphthalein for its dependability and cost-effectiveness.

For those looking to buy O-Cresolphthalein, sourcing from reputable manufacturers in China ensures product quality and consistency. A well-established supplier will provide detailed specifications and reliable delivery. Whether you are conducting routine quality control or complex research, O-Cresolphthalein will undoubtedly enhance the accuracy of your pH measurements. Its application in chemical indicator for titration is a testament to its precise functionality.
