Manufacturing Quality Control of Bis(diphenylphosphino)methane
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC with UV detection | Quantitative determination based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV absorbance at 254 nm. |
| Related Substances | HPLC with UV detection | Separation and quantification of impurities (e.g., mono-substituted phosphines, oxidation products) relative to main peak using gradient elution and UV detection. |
| Residual Solvents | Gas Chromatography (GC-FID) | Identification and quantification of volatile organic solvents (e.g., THF, toluene, methanol) by retention time matching and calibration curve analysis. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration measuring water content via stoichiometric reaction between iodine, sulfur dioxide, and water in pyridine/methanol medium. |
| Heavy Metals | ICP-OES | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion, based on atomic emission intensities at element-specific wavelengths. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride ions using anion-exchange column and suppressed conductivity detection. |
| Phosphine Oxide Content | 31P NMR Spectroscopy | Quantitative identification and integration of characteristic chemical shifts for phosphine oxide versus free phosphine functional groups. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition determination by observing solid-to-liquid phase change under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against defined standards under controlled lighting and viewing conditions. |
| Loss on Drying | Gravimetric Analysis | Mass loss measurement after controlled heating under vacuum or nitrogen to remove volatile components. |
| Acid Value | Acid-Base Titration | Neutralization of acidic impurities (e.g., phosphonic acids) with standardized NaOH solution using phenolphthalein indicator. |
| Bulk Density | Tap Density Measurement | Determination of mass per unit volume after standardized tapping of sample in a calibrated cylinder. |
