Manufacturing Quality Control of 1,3-PHENYLENEDIACETIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies 1,3-phenylenediacetic acid by separation on a reversed-phase column and UV absorbance detection at ~220 nm. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities (e.g., mono-acid, ester, or decarboxylated analogs) using gradient HPLC with UV detection. |
| Residual Solvents | GC-FID | Identifies and quantifies volatile organic solvents (e.g., methanol, toluene, DMF) by gas chromatography with flame ionization detection. |
| Moisture Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration using iodine generation in pyridine-free reagents. |
| Heavy Metals | ICP-OES | Measures total elemental impurities (Pb, Cd, As, Hg, Cr) after acid digestion by optical emission spectroscopy. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Sulfate Impurity | Ion Chromatography | Separates and quantifies sulfate ions using anion-exchange column and conductivity detection. |
| Iron Content | AAS | Quantifies iron after sample digestion using atomic absorption spectroscopy at characteristic wavelength (248.3 nm). |
| pH of Aqueous Suspension | Potentiometric Titration | Measures acidity/basicity of a saturated aqueous suspension using calibrated pH electrode. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid under controlled heating. |
| Loss on Drying | Gravimetric Analysis | Measures mass loss after drying under specified temperature and vacuum conditions. |
| Particle Size Distribution | Laser Diffraction | Analyzes particle size distribution by measuring angular variation in laser light scattering intensity. |
