Manufacturing Quality Control of 4,4'-DIBROMOTRIPHENYLAMINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 254 nm, based on peak area comparison against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification by retention time matching and relative response factors. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify volatile organic solvents (e.g., toluene, THF) based on calibrated external standards. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine generation in pyridine-free reagent; measures water content via stoichiometric reaction with iodine and sulfur dioxide. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element quantification after acid digestion using inductively coupled plasma mass spectrometry with isotope dilution for high sensitivity and accuracy. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride anion using suppressed conductivity detection after eluent generation. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid transition temperature range using controlled heating and optical observation of sample phase change. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of visible particulates or discoloration under standardized white light against a white background. |
| Bulk Density | ASTM D1895 Method A | Measurement of mass per unit volume of freely settled powder using a calibrated graduated cylinder and analytical balance. |
| Particle Size Distribution | Laser Diffraction | Analysis of particle size distribution in dry dispersion mode using Mie scattering theory and validated reference materials. |
| Loss on Drying | Gravimetric Method | Weight loss measured after drying sample at 105 C for 2 hours under vacuum, indicating volatile and moisture content. |
| Residue on Ignition | Sulfated Ash Method | Mass of inorganic residue remaining after controlled charring and ashing at 600 C, expressed as percentage of original sample weight. |
