Selecting the appropriate indicator is crucial for achieving accurate results in complexometric titrations. Among the various metal complex indicators available, o-Cresolphthalein Complexone (CAS 2411-89-4) is highly regarded for its specific applications, particularly with alkaline earth metals. As a specialized manufacturer and supplier, we emphasize the quality and reliability of our chemical offerings. For those looking to buy this indicator, understanding its advantages is key.

Understanding Metal Complex Indicators

Metal complex indicators are compounds that form colored complexes with metal ions. They are used in titrations where a complexing agent, like EDTA, is employed to sequester metal ions. The indicator itself forms a metal-indicator complex that has a different color than the free indicator. At the titration's endpoint, when all the metal ions have been complexed by the titrant, the metal-indicator complex breaks down, releasing the free indicator and causing a distinct color change. O-Cresolphthalein Complexone excels in this role for certain metal ions.

Why O-Cresolphthalein Complexone?

O-Cresolphthalein Complexone (CAS 2411-89-4) is particularly effective for the titration of calcium (Ca) and magnesium (Mg) ions. It exhibits a clear color change within the optimal pH range (8.2-9.8) for these titrations. Its properties, including a purity of ≥97.0% and a molecular weight of 636.61, make it a reliable choice for laboratory analysis, including the determination of calcium in serum. While other indicators exist, o-Cresolphthalein Complexone offers specific advantages for these particular metal ion determinations. As a dedicated supplier, we ensure that our product meets these exacting standards.
