Manufacturing Quality Control of 2-(Diphenylphosphino)-biphenyl
| 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 certified reference standard. |
| Related Substances | HPLC-UV | Identifies and quantifies impurities (e.g., mono-phenyl analogs, oxidation products) using gradient HPLC with UV detection and relative response factors. |
| Residual Solvents | GC-FID | Determines trace organic solvents (e.g., toluene, THF, methanol) by headspace GC with flame ionization detection against calibrated standards. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric titration using iodine generation and stoichiometric reaction with water. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (Pb, Cd, Hg, As, etc.) after acid digestion by inductively coupled plasma mass spectrometry with isotopic detection. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction and filtration. |
| Phosphine Oxide Impurity | 1H NMR Spectroscopy | Detects and semi-quantifies diphenylphosphine oxide by characteristic chemical shift (approx. 13–15 ppm) and integration relative to internal standard. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using calibrated capillary apparatus per USP <741>. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of particulates or phase separation against defined standards under controlled lighting. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing (700–800 C) and weighing. |
| Specific Optical Rotation | Polarimetry | Measures chiral purity (if applicable) via rotation of plane-polarized light in solution at specified concentration and wavelength (e.g., 589 nm). |
| Bulk Density | Tap Density Measurement | Determines mass per unit volume after standardized tapping per ASTM D1895 Method A. |
