Manufacturing Quality Control of 4,6-Dibromodibenzofuran
| 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-DAD | Separates and detects impurities using gradient HPLC with diode-array detection; identification and quantification rely on retention time and spectral matching. |
| Residual Solvents | GC-FID | Determines volatile organic solvents (e.g., toluene, THF) by gas chromatography with flame ionization detection using headspace sampling. |
| Water Content | Karl Fischer Titration | Measures trace water via coulometric or volumetric titration where iodine reacts stoichiometrically with water in a pyridine-methanol solvent system. |
| Heavy Metals (Pb, Cd, Hg, Cr) | ICP-MS | Quantifies elemental impurities at sub-pptr levels by plasma ionization followed by mass spectrometric detection with isotope dilution calibration. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column with suppressed conductivity detection after aqueous extraction. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing (600-700 C) and weighing of the cooled crucible. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube and controlled heating rate. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled white light against established visual standards. |
| Bulk Density | Tap Density Tester | Measures mass per unit volume after standardized mechanical tapping of a known powder mass in a graduated cylinder. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution by measuring angular variation in intensity of laser light scattered by dispersed particles in air or liquid medium. |
| Sulfated Ash | Gravimetric Analysis | Quantifies inorganic sulfate residue after ignition with sulfuric acid pretreatment and subsequent high-temperature incineration and weighing. |
