Manufacturing Quality Control of 4-BROMO-3,3,4,4-TETRAFLUORO-1-BUTENE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantitative determination based on peak area comparison against certified reference standard under optimized chromatographic conditions. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatile impurities are equilibrated in headspace vial and quantified by GC-FID using calibration curves. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine generated coulometrically reacts stoichiometrically with water in the sample. |
| Acid Value | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution with phenolphthalein endpoint detection. |
| Halogen Content (Total Bromine) | Oxygen Flask Combustion followed by Potentiometric Titration | Sample combusted in oxygen flask; bromine converted to bromide, then titrated with silver nitrate using potentiometric endpoint. |
| Heavy Metals (Pb, Cd, Hg, Cr, As) | ICP-MS | Sample digested and elemental concentrations measured by inductively coupled plasma mass spectrometry with isotope dilution or external calibration. |
| Non-Volatile Residue | Gravimetric Analysis | Sample evaporated to dryness at controlled temperature; residue weighed after cooling in desiccator. |
| Color | APHA Color Scale (Visual or Spectrophotometric) | Comparison of sample color intensity against platinum-cobalt standard solutions using visual assessment or spectrophotometric absorbance at 455 nm. |
| Density | Digital Density Meter (Oscillating U-tube) | Density determined from resonant frequency shift of a vibrating U-shaped tube filled with sample at controlled temperature. |
| Refractive Index | Digital Refractometer | Measurement of light refraction angle at air-sample interface at specified temperature (e.g., 20 C) to calculate refractive index. |
| Chloride Impurity | Ion Chromatography (IC) with Conductivity Detection | Separation of chloride anions on ion-exchange column followed by quantitative detection via conductivity measurement. |
| Stability-Indicating Impurities | HPLC with UV Detection | Separation and quantification of structurally related degradation products using reversed-phase HPLC and UV absorbance at appropriate wavelength. |
