Manufacturing Quality Control of meso-1,2-Diphenylethylenediamine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 254 nm, based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies impurities (e.g., mono-benzylated intermediates, oxidation products) using gradient HPLC-UV with relative response factors. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric titration using iodine generated in situ; reaction stoichiometry is 1:1 with water. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing (700-800 C) and weighing of the cooled crucible. |
| Heavy Metals | ICP-OES | Quantifies Pb, Cd, Hg, As, and other regulated metals after acid digestion, using plasma emission intensity at element-specific wavelengths. |
| Chloride Content | Potentiometric Titration | Titrates chloride ions with silver nitrate using a silver indicator electrode; endpoint detected by potential inflection. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light at 20 C using sodium D-line (589 nm); indicates enantiomeric excess and identity. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using calibrated capillary tube method per USP <741>. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity of sample against standard white background under controlled lighting. |
| Solubility | Qualitative Solubility Test | Evaluates complete dissolution in specified solvents (e.g., ethanol, methanol) at defined concentration and temperature. |
| pH of Aqueous Solution | pH Meter | Measures hydrogen ion activity in saturated aqueous suspension using calibrated glass electrode system. |
| Loss on Drying | Thermogravimetric Analysis (TGA) | Determines volatile content by measuring mass loss upon heating to 105 C under nitrogen for 2 hours. |
