In the realm of analytical chemistry, the accuracy of experimental results hinges on the quality of reagents used. For complexometric titrations, selecting the appropriate metal indicator is paramount. O-Cresolphthalein Complexone (CAS: 2411-89-4) stands out as a highly effective indicator, particularly favored for its performance in the determination of alkaline earth metals such as calcium and magnesium. As a leading manufacturer and supplier of fine chemicals, we understand the critical role this compound plays in various scientific disciplines.

O-Cresolphthalein Complexone is a phthalein dye that exhibits a distinct color transition, typically from colorless at a pH of 8.2 to red at a pH of 9.8. This characteristic makes it an excellent visual aid for pinpointing the endpoint in complexometric titrations, where a chelating agent, commonly EDTA, is used to titrate metal ions. When bound to metal ions like Ca2+ or Mg2+ in an alkaline solution, it forms a colored complex. As the titrant consumes the free metal ions, the indicator is released, signaling the completion of the reaction through a sharp color change.

The primary application for O-Cresolphthalein Complexone lies in the accurate quantification of calcium in biological fluids, such as serum and plasma. This is crucial in clinical pathology for diagnosing various health conditions. Furthermore, its utility extends to water quality testing and other industrial analyses where precise metal ion concentration is required. If you are looking to buy O-Cresolphthalein Complexone, choosing a reputable manufacturer ensures you receive a product with consistent purity and performance, which directly impacts the reliability of your analytical data.
