Manufacturing Quality Control of 2,3-DibroMo-1,4-difluorobenzene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component by retention time and peak area comparison against certified reference standard. |
| Related Substances | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and semi-quantifies impurities based on mass spectral fragmentation patterns and retention behavior. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Measures volatile organic solvents (e.g., dichloromethane, toluene) using equilibrium vapor phase analysis. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Determines trace water via electrochemical iodine generation and stoichiometric reaction with water. |
| Acid Value | Acid-Base Titration (NaOH standard solution) | Measures acidic impurities by titration with standardized sodium hydroxide in alcoholic medium. |
| Heavy Metals (Pb, Cd, Hg, As) | Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) | Quantifies elemental metal impurities after acid digestion and plasma excitation. |
| Chloride Content | Ion Chromatography (IC) with conductivity detection | Separates and quantifies chloride ions using anion-exchange column and suppressed conductivity detection. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating crystallinity and purity. |
| Appearance | Visual Inspection (in glass vial under controlled lighting) | Assesses physical state, color, and presence of particulates or phase separation against defined standards. |
| Bulk Density | ASTM D1895 Method A (Tapped density) | Measures mass per unit volume after standardized tapping to evaluate flow and handling characteristics. |
| Loss on Drying (LOD) | Gravimetric Analysis (105 C, 2 h) | Determines volatile content by weight loss after controlled heating and desiccation. |
| Residue on Ignition | Gravimetric Analysis (550 C, 30 min) | Measures non-volatile inorganic residue after high-temperature ashing of organic matrix. |
