Manufacturing Quality Control of 1,3-Dibromo-2,5-difluorobenzene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantitative determination based on peak area comparison against a certified reference standard under optimized chromatographic conditions. |
| Related Substances | Gas Chromatography-Mass Spectrometry (GC-MS) | Separation and identification of impurities by retention time and mass spectral fragmentation patterns. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatile solvent residues quantified via equilibrium partitioning into headspace followed by GC-FID analysis. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine is generated in situ to react stoichiometrically with water. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) | Multi-element detection based on characteristic atomic emission lines after high-temperature plasma atomization. |
| Chloride Impurity | Ion Chromatography (IC) with conductivity detection | Anion separation on ion-exchange column followed by quantitative detection via electrical conductivity. |
| Residue on Ignition | Gravimetric Analysis (Sulfated Ash method) | Mass of non-volatile inorganic residue determined after controlled ignition at 700-800 C following sulfuric acid treatment. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as the temperature range over which solid transforms to liquid under standardized heating rate. |
| Appearance | Visual Inspection (in glass vial under controlled lighting) | Assessment of physical state, color, and presence of particulates or phase separation against specified criteria. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral molecules in solution (though compound is achiral, test confirms absence of optically active contaminants). |
| Bulk Density | USP <616> Tap Density method | Determined as mass per unit volume after mechanical tapping to achieve reproducible packing. |
| Particle Size Distribution | Laser Diffraction (Dry Dispersion) | Size distribution derived from angular scattering pattern of laser beam passing through dispersed particles. |
