Manufacturing Quality Control of 1,4-dibromonaphthalene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies 1,4-dibromonaphthalene peak area relative to calibration standards using retention time and response factor. |
| Related Substances | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and semi-quantifies impurities based on mass spectral fragmentation patterns and retention times. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Measures volatile organic solvents by equilibrium partitioning into headspace followed by GC separation and detection. |
| Moisture Content | Karl Fischer Titration | Determines water content via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Acid Value | Acid-Base Titration with NaOH | Measures acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Heavy Metals | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Quantifies metal impurities (e.g., Pb, Cd, Hg, As) by atomization and emission intensity measurement at characteristic wavelengths. |
| Chloride Content | Potentiometric Titration with AgNO3 | Detects chloride ions by precipitation titration with silver nitrate using silver electrode for endpoint detection. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating crystallinity and purity. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled white light against standard references. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and weighing. |
| Bulk Density | Tap Density Tester | Determines mass per unit volume of powder under standardized tapping conditions. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of solid particles by analyzing angular scattering pattern of laser beam passing through dispersed sample. |
