Key Features and Chemical Profile
O-Cresolphthalein Complexone presents as a fine white to off-white powder, offering excellent stability for storage and handling. Its chemical structure (C32H32N2O12) corresponds to a molecular weight of 636.61. The compound's utility as an indicator is most pronounced within a specific pH range, typically from 8.2 to 9.8, where it transitions from colorless to red. This distinct colorimetric response is crucial for its applications in complexometric titrations, allowing for the clear identification of endpoints. With an assay of ≥97.0%, our product ensures the accuracy required for demanding analytical procedures.
Applications in Complexometric Titrations and Beyond
The primary application for o-Cresolphthalein Complexone is as an indicator in complexometric titrations, particularly for determining the concentration of alkaline earth metal ions like calcium (Ca) and magnesium (Mg). When these ions are present, the indicator forms a stable, colored complex, signaling the completion of the titration. Its use extends to the determination of calcium in biological samples, such as serum, where accurate measurement is critical for diagnostic purposes.
