Manufacturing Quality Control of bis(4-bromophenyl) sulphide
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities (e.g., mono-bromo analogs, dibenzothiophene, bromobenzene) using gradient HPLC-UV with a C18 column. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify residual solvents (e.g., toluene, DMF, methanol) based on calibrated external standards. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine water content via stoichiometric reaction with water. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification after acid digestion; detection based on characteristic atomic emission wavelengths in inductively coupled plasma. |
| Chloride Impurity | Ion Chromatography | Separation of chloride ions on an anion-exchange column with suppressed conductivity detection, using sodium carbonate/bicarbonate eluent. |
| Sulfur Content | Combustion IC | High-temperature combustion followed by ion chromatographic detection of sulfate ions generated from organic sulfur oxidation. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as the temperature at which solid phase fully converts to liquid. |
| Appearance | Visual Inspection | Assessment under controlled white light against standard color/opacity references for clarity, color, and absence of particulates. |
| Residue on Ignition | Gravimetric Analysis | Mass difference measured before and after high-temperature ashing (700-800 C) to determine inorganic residue content. |
| Bulk Density | Tap Density Tester | Measured mass per unit volume after standardized tapping of a known powder sample in a graduated cylinder. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity patterns to calculate volume-based particle size distribution in dry or wet dispersion mode. |
