Manufacturing Quality Control of 2-BROMODIBENZOTHIOPHENE
| 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-DAD | Separates and detects impurities using gradient HPLC coupled with diode array detection for spectral confirmation and relative quantification. |
| Residual Solvents | GC-FID | Determines volatile organic solvents (e.g., toluene, THF) by gas chromatography with flame ionization detection using headspace sampling. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric titration where iodine reacts stoichiometrically with water in anhydrous methanol-based medium. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Quantifies trace heavy metals after acid digestion using inductively coupled plasma mass spectrometry with isotope-dilution calibration. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction and filtration. |
| Sulfate Impurity | Ion Chromatography | Detects sulfate ions via anion-exchange chromatography with suppressed conductivity detection following sample dissolution and dilution. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing (700-800 C) and precise weighing of the cooled crucible. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube method per USP <741>. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled white light against standard reference samples. |
| Bulk Density | Tap Density Tester | Measures mass per unit volume after standardized tapping (e.g., 100 taps) of a known powder mass in a graduated cylinder. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution of dry powder using Mie scattering theory applied to laser light diffraction patterns generated by dispersed particles. |
