Manufacturing Quality Control of 1-Bromo-4-chloronaphthalene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies 1-chloro-4-bromonaphthalene peak area relative to a calibration curve using an internal or external standard. |
| Related Substances | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and semi-quantifies impurities based on retention time and mass spectral fragmentation patterns. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Detects and quantifies volatile organic solvents by analyzing vapor phase above the sample at controlled temperature. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric titration based on iodine consumption in a pyridine-methanol solvent system. |
| Acid Value | Acid-Base Titration with NaOH | Determines acidic impurities by titrating with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Halogen Content (Cl, Br) | Oxygen Flask Combustion followed by Ion Chromatography (IC) | Converts organohalogens to halide ions by combustion, then quantifies Cl- and Br- separately via IC conductivity detection. |
| Heavy Metals | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Quantifies metal impurities (e.g., Pb, Cd, Hg, As) after acid digestion by measuring element-specific emission wavelengths. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity of molten or dissolved sample against standard references under controlled lighting. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating purity and identity via depression behavior. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and cooling in a desiccator. |
| Chloride Ion (Inorganic) | Ion Chromatography (IC) | Quantifies free chloride ion after aqueous extraction, using conductivity detection and anion exchange column. |
| Volatility Loss | Thermogravimetric Analysis (TGA) | Measures mass loss under controlled heating to assess thermal stability and low-boiling impurity content. |
