Manufacturing Quality Control of 1-BROMO-3-ETHYLBENZENE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies 1-bromo-3-ethylbenzene peak area relative to a calibration curve using an internal or external standard. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration based on the stoichiometric reaction of iodine with water in pyridine/methanol medium. |
| Residue on Evaporation | Gravimetric Analysis | Evaporates a known sample mass under controlled conditions and weighs non-volatile residue. |
| Acidity (as HBr) | Acid-Base Titration with NaOH | Neutralizes acidic impurities (e.g., residual HBr) using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color | APHA Color Scale (Visual or Spectrophotometric) | Compares sample color to platinum-cobalt standard solutions or measures absorbance at 455 nm. |
| Density at 20 C | Digital Density Meter | Determines mass per unit volume using oscillating U-tube principle with temperature-controlled measurement. |
| Refractive Index at 20 C | Refractometry | Measures bending of light through sample at specified wavelength (typically 589 nm) to infer purity and composition. |
| Non-Volatile Matter | Gravimetric Analysis | Evaporates solvent and volatile components from a weighed sample, then dries and reweighs residue. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after acid digestion by measuring atomic absorption of characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Residual Solvents (e.g., ethanol, toluene) | Gas Chromatography (GC) with FID or MS detector | Separates and quantifies volatile organic impurities using headspace or direct injection GC. |
| Odor | Sensory Evaluation | Assesses presence of off-odor indicative of degradation or contamination by trained personnel under controlled conditions. |
