Manufacturing Quality Control of 1-Bromo-4-chloro-2,5-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 retention time and characteristic mass spectra. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Detects volatile organic solvents by equilibrium partitioning into headspace followed by GC separation. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Measures water via electrochemical generation of iodine reacting stoichiometrically with water in anhydrous medium. |
| Acidity (as HCl) | Acid-Base Titration with NaOH | Determines acidic impurities by titration with standardized sodium hydroxide using potentiometric endpoint detection. |
| Heavy Metals (Pb, Cd, Hg, As) | Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) | Quantifies trace metals after acid digestion by measuring element-specific atomic emission intensities. |
| Chloride Ion (Cl-) | Ion Chromatography (IC) with conductivity detection | Separates and quantifies chloride anions using ion-exchange column and suppressed conductivity detection. |
| Residue on Ignition | Gravimetric Analysis (Sulfated Ash) | Measures non-volatile inorganic residue after high-temperature incineration and weighing. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity against standard reference under controlled lighting conditions. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube method. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light caused by chiral impurities or enantiomeric excess. |
| Density | Digital Density Meter (Oscillating U-tube) | Determines mass per unit volume based on resonant frequency shift of vibrating U-shaped tube filled with sample. |
