Manufacturing Quality Control of 4-Bromo-4'-hydroxybiphenyl
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reverse-phase HPLC with UV detection at 254 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities by gradient HPLC-UV against qualified reference standards or threshold-based reporting. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., methanol, toluene, DMF) based on calibrated response factors. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine generation in pyridine-free reagent to determine trace water by stoichiometric reaction. |
| Heavy Metals | ICP-MS | Multi-element quantification of Pb, Cd, Hg, As, and others after acid digestion, using isotopic detection for sub-ppb sensitivity. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride ions after sample dissolution and filtration; quantified against NaCl calibration curve. |
| Residue on Ignition | Gravimetric Analysis | Weighing residue remaining after high-temperature ashing (700-800 C) to assess inorganic ash content. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid transition temperature range using calibrated capillary apparatus per USP <741>. |
| Appearance | Visual Inspection | Assessment of crystalline form, color, and absence of visible particulates or discoloration under controlled white light. |
| Loss on Drying | Thermogravimetric Analysis | Measurement of mass loss upon heating to 105 C for 2 hours to determine volatile content including adsorbed moisture. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a defined suspension (e.g., 1% w/v in water) using calibrated electrode to detect acidic/basic degradation products. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder dispersion via laser scattering to determine D10, D50, D90 values per ISO 13320. |
