Manufacturing Quality Control of PHENOLPHTHALEIN COMPLEXONE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purified Phenolphthalein Complexing Agent) | UV-Vis Spectrophotometry | Quantifies active component based on characteristic absorbance at λ~550 nm in alkaline medium, using a calibrated standard curve. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Measures total heavy metal content by atomizing the sample and quantifying ground-state metal atom absorption at element-specific wavelengths. |
| Chloride Impurity | Potentiometric Titration with AgNO₃ | Determines chloride concentration via precipitation titration using silver nitrate and a silver indicator electrode. |
| Sulfate Impurity | Gravimetric Analysis | Precipitates sulfate as BaSO₄ under controlled conditions; mass of dried precipitate correlates to sulfate content. |
| Loss on Drying (LOD) | Thermogravimetric Analysis (TGA) or Oven Drying | Measures volatile content (e.g., moisture, solvents) as mass loss after heating to 105 °C under specified time/atmosphere. |
| pH (1% aqueous solution) | pH Potentiometry | Determines hydrogen ion activity using a calibrated glass electrode in a standardized aqueous suspension. |
| Residue on Ignition | Gravimetric Analysis (Sulfated Ash) | Quantifies non-volatile inorganic impurities by ignition of residue at 700–800 °C followed by weighing. |
| Related Substances (Impurity Profile) | High-Performance Liquid Chromatography (HPLC) | Separates and quantifies structurally related impurities using reversed-phase C18 column and UV detection. |
| Iron (Fe) Content | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Determines trace iron via plasma excitation and measurement of element-specific emission intensities. |
| Appearance (Color & Clarity) | Visual Inspection against Standard Solutions | Assesses physical state, color intensity (e.g., APHA scale), and absence of particulates in solution under controlled lighting. |
| Solubility in Water/Ethanol | Qualitative Solubility Test | Evaluates complete dissolution in specified solvents at defined temperature and concentration per USP/EP general chapter <281>. |
