Manufacturing Quality Control of 2,2'-DIBROMOBIPHENYL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 254 nm based on peak area comparison to reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies impurities (e.g., mono-brominated, debrominated, or oxidized analogs) using gradient HPLC-UV against qualified impurity standards. |
| Residual Solvents | GC-FID | Measures trace organic solvents (e.g., toluene, isopropanol) by gas chromatography with flame ionization detection using internal standard calibration. |
| Moisture Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration using iodine generation and stoichiometric reaction with water. |
| Heavy Metals (as Pb) | ICP-OES | Quantifies total heavy metals (Pb, Cd, Hg, As, Cr) after acid digestion using inductively coupled plasma optical emission spectroscopy. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column with conductivity detection and external calibration. |
| 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 visible particulates or discoloration against white/black background under controlled lighting. |
| Bulk Density | ASTM D1895 Method A | Measures mass per unit volume of freely settled powder using a standardized graduated cylinder and balance. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution of solid particles in air dispersion using Mie scattering theory and calibrated instrument. |
| Ash Content | Gravimetric Analysis | Measures inorganic residue after high-temperature incineration (550-600 C) followed by weighing of residual ash. |
| Bromine Content | Oxidative Combustion followed by Potentiometric Titration | Determines total bromine by combustion in oxygen, absorption in alkali, and titration of bromide with silver nitrate using potentiometric endpoint detection. |
