Manufacturing Quality Control of 1,2-Phenylenediacetic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration with NaOH | Quantifies carboxylic acid groups by neutralization with standardized sodium hydroxide solution using phenolphthalein or potentiometric endpoint detection. |
| Moisture Content | Karl Fischer Titration | Determines water content via stoichiometric reaction between water, iodine, sulfur dioxide, and a base in methanol medium. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of visible particulates or foreign matter against standard reference under controlled lighting. |
| Melting Point | Capillary Melting Point Apparatus | Measures temperature range at which solid transitions to liquid, indicating purity and identity based on sharpness and agreement with literature value. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic impurities by high-temperature ashing followed by weighing of residual ash. |
| Heavy Metals | Colorimetric Sulfide Precipitation (USP <231>) | Detects total heavy metals (as Pb) by formation of colored metal sulfide complexes in acidic medium, compared visually to lead standard. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column with conductivity detection. |
| Sulfate Impurity | Barium Sulfate Gravimetry | Precipitates sulfate as BaSO4 in acidic medium; mass of dried precipitate correlates to sulfate content. |
| Related Substances | Reverse-Phase HPLC with UV Detection | Separates and quantifies structurally similar impurities using C18 column and UV absorbance at 210–230 nm. |
| Iron Content | Atomic Absorption Spectroscopy (AAS) | Quantifies iron by measuring absorption of specific wavelength light by ground-state Fe atoms in acetylene-air flame. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Drying | Measures mass loss upon heating under controlled conditions to determine volatile components including residual solvents and water. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determines acidity/basicity of saturated aqueous suspension using calibrated pH electrode and meter. |
