Manufacturing Quality Control of 1,2-Diphenylethylenediamine
| 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. |
| Related Substances | HPLC-UV | Separation and quantification of impurities (e.g., mono-benzylated intermediates, oxidation products) relative to main peak using gradient elution. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents (e.g., methanol, toluene, THF) by gas chromatographic separation with flame ionization detection. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration measuring water via stoichiometric reaction with iodine, sulfur dioxide, and base in anhydrous methanol/pyridine medium. |
| Heavy Metals | ICP-MS | Multi-element detection and quantification of toxic metals (Pb, Cd, Hg, As) after acid digestion, based on mass-to-charge ratio detection. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using suppressed conductivity detection after alkaline eluent separation. |
| Optical Rotation | [alpha]D Measurement | Determination of specific rotation using sodium D-line light (589 nm) in solution to confirm chiral integrity and enantiomeric purity. |
| 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 of solid sample against established visual standards under controlled lighting. |
| Residue on Ignition | Gravimetric Analysis | Weighing of non-volatile inorganic residue remaining after high-temperature ashing (700-800 C) of sample. |
| pH of Aqueous Solution | pH Meter | Measurement of hydrogen ion activity in a saturated aqueous suspension using calibrated glass electrode system. |
