Manufacturing Quality Control of 1,5-DIBROMO-2,4-DIFLUOROBENZENE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantitative determination based on peak area comparison against certified reference standard under optimized chromatographic conditions. |
| Related Substances | Gas Chromatography (GC) with FID or MS detection | Separation and semi-quantitative/quantitative analysis of impurities using retention time and relative response factors. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatile solvent residues quantified by equilibrium partitioning into headspace followed by GC-FID analysis. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated coulometrically reacts stoichiometrically with water in the sample. |
| Acid Value | Acid-Base Titration with NaOH standard solution | Neutralization of acidic impurities (e.g., HBr) using standardized sodium hydroxide solution with potentiometric endpoint detection. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Multi-element quantification after acid digestion, based on element-specific atomic emission intensities. |
| Chloride Impurity | Ion Chromatography (IC) with conductivity detection | Separation and quantification of chloride anions via ion-exchange chromatography and suppressed conductivity measurement. |
| Melting Point | Capillary Melting Point Determination | Thermal transition observed as solid-to-liquid phase change using calibrated capillary apparatus per USP <741>. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against standard white background under controlled lighting. |
| Residue on Ignition | Gravimetric Analysis (Sulfated Ash) | Mass of non-volatile inorganic residue remaining after high-temperature incineration and sulfuric acid treatment. |
| Bulk Density | Tap Density Measurement (ASTM D1895) | Determined by measuring mass per unit volume after standardized tapping of a known powder sample in a graduated cylinder. |
| Particle Size Distribution | Laser Diffraction (Dry Dispersion) | Analysis of scattered laser light intensity pattern to calculate size distribution based on Mie scattering theory. |
