Manufacturing Quality Control of 4-BROMO-4'-ETHYLBIPHENYL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Related Substances | HPLC-DAD | Separation and identification of impurities based on retention time and UV spectral match; quantified relative to main peak. |
| Residual Solvents | GC-FID | Volatile organic solvents separated by capillary GC and detected via flame ionization; quantified using external calibration. |
| Moisture Content | Karl Fischer Titration | Coulometric or volumetric titration where iodine reacts stoichiometrically with water in anhydrous methanol-based reagent. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element detection after acid digestion; emission intensity at characteristic wavelengths correlates with metal concentration. |
| Chloride Impurity | Ion Chromatography | Separation of chloride anions on anion-exchange column with suppressed conductivity detection. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid transition temperature range using calibrated capillary apparatus per USP <741>. |
| Loss on Drying | Gravimetric (Thermogravimetric) | Mass loss measured after drying under controlled temperature and vacuum per USP <731>. |
| Residue on Ignition | Sulfated Ash Test | Inorganic residue mass determined after high-temperature ignition following sulfuric acid treatment per USP <281>. |
| Particle Size Distribution | Laser Diffraction | Scattering pattern analysis of dispersed particles in liquid medium to calculate size distribution. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution, indicating chiral purity. |
| pH of Aqueous Suspension | pH Meter | Electrochemical measurement of hydrogen ion activity in a saturated aqueous suspension prepared per compendial method. |
