Manufacturing Quality Control of 4-BROMO-1-CHLORO-2-ETHYLBENZENE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard under optimized chromatographic conditions. |
| Related Substances | Gas Chromatography (GC) with FID detection | Separation and quantification of structurally similar impurities using retention time matching and relative response factors. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) with FID | Volatile organic solvents are partitioned into headspace and quantified by calibration against standard solutions. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water in the sample. |
| Chloride Content | Ion Chromatography (IC) | Separation of chloride anions on an ion-exchange column followed by conductivity detection and quantification. |
| Heavy Metals (Pb, Cd, Hg, Cr, As) | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Atomization and ionization of sample in plasma, followed by mass-selective detection of metal isotopes. |
| Residue on Ignition | Gravimetric Analysis | Mass of non-volatile inorganic residue determined after high-temperature ashing and cooling in a desiccator. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as the temperature range at which solid-to-liquid phase change occurs under controlled heating. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against established reference standards under controlled lighting. |
| Acid Value | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution with phenolphthalein endpoint detection. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral components in solution at specified concentration and path length. |
| Bulk Density | Tap Density Measurement | Mass per unit volume determined after standardized tapping of a known mass in a calibrated cylinder. |
