Manufacturing Quality Control of 1,3-Difluoro-5-iodobenzene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | GC-FID | Quantifies main component using flame ionization detection after gas chromatographic separation. |
| Related Substances | GC-MS | Identifies and quantifies impurities by mass spectral fragmentation patterns following GC separation. |
| Residual Solvents | GC-FID with headspace sampling | Detects volatile organic solvents based on partitioning into headspace and FID response. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between iodine, sulfur dioxide, and water in methanol-pyridine medium. |
| Heavy Metals | ICP-OES | Determines trace metal contaminants by measuring atomic emission intensities after plasma atomization/excitation. |
| Iodine Content | Potentiometric Titration with sodium thiosulfate | Quantifies iodine via redox titration where iodine is reduced to iodide and endpoint detected by potential change. |
| Acid-Base Impurities | Non-aqueous Acid-Base Titration | Titrates acidic or basic impurities in anhydrous solvent using perchloric acid or sodium methoxide as titrant. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and weighing. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube method. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity against standard reference under controlled lighting conditions. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light caused by chiral impurities or enantiomeric excess in solution. |
