Apexbio Technology LLC Phenolphthalein 77-09-8 1g
SDP

Phenolphthalein (77-09-8) is a synthetic organic compound commonly applied as a pH indicator in analytical chemistry particularly for acid-base titration assays Phenolphthalein exerts its activity through a protonation deprotonation equilibrium resulting in a colorimetric shift from colorless (acidic) to pink (alkaline) within a pH range of 8 3 to 10 0 In biomedical research phenolphthalein is used in presumptive forensic blood detection tests leveraging the peroxidase-like catalysis of hemoglobin to mediate oxidation reactions that yield characteristic color changes Based on these properties phenolphthalein is applicable in analytical chemistry and forensic investigations Potential carcinogenic risks have prompted caution in its laboratory handling and application
