Manufacturing Quality Control of 2-Bromostyrene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies 2-bromostyrene peak area relative to internal or external standard using retention time and calibration curve. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic impurities by weighing residue after high-temperature ashing. |
| Acidity (as HBr) | Acid-Base Titration with NaOH | Neutralizes acidic impurities (e.g., HBr) using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color | Visual Comparison or Hazen (APHA) Scale | Evaluates color intensity by comparing sample appearance against platinum-cobalt standard solutions. |
| Density at 20 C | Digital Density Meter | Measures mass per unit volume using oscillating U-tube principle calibrated with air and water. |
| Refractive Index at 20 C | Refractometry | Determines refractive index based on critical angle of total internal reflection using sodium D-line light. |
| Heavy Metals (as Pb) | ICP-OES | Quantifies trace heavy metals after acid digestion by measuring element-specific atomic emission intensities. |
| Chlorinated Impurities (e.g., o-chlorostyrene) | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and quantifies structural analogs via retention time and characteristic ion fragments. |
| Aldehyde Impurities (e.g., benzaldehyde) | Derivatization GC-FID | Converts aldehydes to stable hydrazones followed by separation and FID detection. |
| Non-Volatile Residue | Evaporation and Gravimetry | Measures volatile loss by evaporating known mass under controlled conditions and weighing residual solids. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light caused by chiral impurities or enantiomeric excess (though compound is achiral, detects chiral contaminants). |
