Manufacturing Quality Control of 4,4''-Dibromo-p-terphenyl
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 254 nm, comparing peak area to calibrated standard. |
| Related Substances | HPLC-DAD | Detects and quantifies impurities (e.g., mono-bromo, tri-bromo analogs) via HPLC with diode-array detection and spectral confirmation. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents (e.g., toluene, xylene) using gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric titration based on iodine consumption in pyridine-methanol buffer. |
| Heavy Metals (as Pb) | ICP-OES | Measures total heavy metal content (Pb, Cd, Hg, As) after acid digestion using inductively coupled plasma optical emission spectrometry. |
| Chloride Impurity | Ion Chromatography | Quantifies chloride ions eluted from anion-exchange column with suppressed conductivity detection. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using calibrated capillary tube under controlled heating rate. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of visible particulates or discoloration against white background under controlled lighting. |
| Bulk Density | ASTM D1895 Method A | Measures mass per unit volume of freely settled powder using standardized graduated cylinder and balance. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution of dry powder via light scattering pattern generated by dispersed particles in air stream. |
| Ash Content | Gravimetric Analysis | Determines inorganic residue after high-temperature incineration (550-600 C) and weighing of residual ash. |
| Loss on Drying | Thermogravimetric Analysis | Measures weight loss upon heating to 105 C for 2 hours, indicating volatile and moisture content. |
