Manufacturing Quality Control of 4-Bromo-4'-iodobiphenyl
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities (e.g., mono-halogenated, di-bromo, di-iodo, or debrominated analogs) using gradient HPLC-UV. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., toluene, DMF, methanol) based on retention time and calibration curves. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine generated electrochemically to react stoichiometrically with water in the sample. |
| Heavy Metals (Pb, Cd, Hg, Cr) | ICP-MS | Multi-element quantification after acid digestion by measuring metal isotopes via inductively coupled plasma mass spectrometry. |
| Residue on Ignition | Gravimetric Analysis | Mass measurement of inorganic residue remaining after high-temperature ashing (700-800 C) of the sample. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using suppressed conductivity detection after aqueous extraction. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range over which solid-to-liquid phase transition occurs, using calibrated capillary method. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under controlled white-light illumination against standard references. |
| Bulk Density | USP <616> Tap Density Method | Measurement of mass per unit volume after standardized tapping of a known mass in a graduated cylinder. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity as a function of angle to derive volume-based particle size distribution. |
| Organic Volatile Impurities (OVI) | GC-MS | Identification and quantification of low-level volatile organic impurities using gas chromatography coupled with mass spectrometric detection. |
