Manufacturing Quality Control of 4,4'-Diiodobiphenyl
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies 4,4'-diiodobiphenyl peak area against a calibrated standard curve using UV detection. |
| Related Substances | HPLC-UV | Separates and quantifies impurities (e.g., mono-iodo, tri-iodo, or biphenyl derivatives) relative to main peak. |
| Residual Solvents | GC-FID | Detects and quantifies volatile organic solvents (e.g., toluene, DMF) by flame ionization detection after headspace or direct injection. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric titration with iodine generated electrochemically or added stoichiometrically. |
| Heavy Metals (as Pb) | ICP-OES | Quantifies total heavy metals (Pb, Cd, Hg, As) after acid digestion by measuring atomic emission intensities at characteristic wavelengths. |
| Iodide Ion Impurity | Ion Chromatography | Separates and detects free iodide ions using anion-exchange column and conductivity detection. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using controlled heating and visual observation. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under standardized lighting and viewing conditions. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic residue mass after high-temperature ashing of sample in a platinum crucible. |
| Chloride Impurity | Potentiometric Titration | Quantifies chloride ions using silver nitrate titrant and silver/silver chloride indicator electrode. |
| Bulk Density | Tap Density Tester | Measures mass per unit volume after standardized tapping of powder in a graduated cylinder. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution by analyzing angular scattering pattern of laser light passed through dispersed particles. |
