Manufacturing Quality Control of 1,2-BIS(DIPHENYLPHOSPHINO)BENZENE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase chromatography with UV detection at 254 nm based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Separates and quantifies impurities (e.g., mono-substituted analogs, oxidation products) using gradient elution and UV detection. |
| Residual Solvents | GC-FID | Detects and quantifies volatile organic solvents (e.g., toluene, THF, methanol) by gas chromatography with flame ionization detection. |
| Moisture Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration using iodine generation in pyridine-free reagent system. |
| Heavy Metals | ICP-OES | Measures trace metal contaminants (e.g., Pd, Ni, Fe, Cu) after acid digestion by optical emission spectroscopy at element-specific wavelengths. |
| Chloride Content | Ion Chromatography | Quantifies chloride ions using suppressed conductivity detection after separation on an anion-exchange column. |
| Phosphorus Content | ICP-OES | Verifies stoichiometric phosphorus content by measuring total phosphorus after microwave-assisted digestion. |
| 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 presence of foreign particles against established reference standards under controlled lighting. |
| Solubility | Qualitative Dissolution Test | Evaluates complete dissolution in specified solvents (e.g., chloroform, toluene) at room temperature within defined time. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing (700-800 C) and weighing. |
| Optical Rotation | Polarimetry | Determines specific rotation using sodium D-line light to confirm chiral purity and absence of racemization. |
