Manufacturing Quality Control of DIPHENYL(O-TOLYL)PHOSPHINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component peak area relative to calibration curve using internal or external standard. |
| Related Substances | Gas Chromatography (GC) with FID or MS detection | Separates and quantifies impurities based on retention time and response relative to main compound. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric titration using iodine-sulfur dioxide reaction. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by high-temperature incineration followed by weight measurement. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Measures trace metal concentrations after acid digestion by detecting element-specific emission wavelengths. |
| Acid Value | Acid-Base Titration with NaOH | Determines acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Phosphorus Content | UV-Vis Spectrophotometry (after oxidation) | Measures phosphomolybdate complex absorbance at ~820 nm following wet oxidation to orthophosphate. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity against standard reference under controlled lighting. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary method. |
| Solubility in Common Solvents | Qualitative Dissolution Test | Evaluates complete dissolution in specified solvents (e.g., toluene, THF) at defined temperature and concentration. |
| Volatile Matter | Thermogravimetric Analysis (TGA) | Measures mass loss upon controlled heating to quantify low-boiling or thermally labile components. |
