Manufacturing Quality Control of 4-Methoxyisophthalic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based solvent system. |
| Residue on Ignition | Gravimetric Analysis | Heating to 700-800 C to combust organic matter, then weighing inorganic residue as sulfate ash. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element detection via plasma excitation and emission spectroscopy after acid digestion and dilution. |
| Chloride Impurity | Ion Chromatography | Separation of chloride anions on an ion-exchange column with conductivity detection. |
| Sulfate Impurity | Barium Sulfate Gravimetry | Precipitation of sulfate as BaSO4 under controlled pH and temperature, followed by drying and weighing. |
| Related Substances | HPLC-DAD | Identification and quantification of structurally similar impurities using diode-array detection and retention time matching. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement by observing solid-to-liquid phase change in a capillary tube under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against standard white background under controlled lighting. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | Determination of hydrogen ion activity in a saturated aqueous suspension using calibrated glass electrode. |
| Organic Volatile Impurities | GC-FID | Separation and quantification of residual solvents by gas chromatography with flame ionization detection. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity to derive size distribution based on Mie theory. |
