Manufacturing Quality Control of EthyltributylphosphoniuM broMide
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component peak area relative to calibration curve using volatile, thermally stable derivatives. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between iodine, sulfur dioxide, and water in methanol/pyridine medium. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic impurities by ashing sample at 500-600 C and weighing residual mass. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride anions based on ion exchange retention and conductivity detection. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Atomizes and excites sample in plasma; measures element-specific emission intensities for multi-element quantification. |
| Acid Value | Acid-Base Titration with NaOH | Neutralizes acidic impurities (e.g., HBr, phosphonic acids) using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color | Visual Comparison or Spectrophotometry (APHA scale) | Evaluates yellowness/browning by comparing sample color to platinum-cobalt standard solutions or measuring absorbance at 430 nm. |
| Specific Gravity | Digital Density Meter | Determines density ratio relative to water at 20 C using oscillating U-tube principle. |
| Phosphorus Content | UV-Vis Spectrophotometry (after ammonium molybdate reduction) | Measures phosphomolybdenum blue complex absorbance after oxidative digestion and reduction. |
| Volatile Organic Impurities | Headspace GC-MS | Identifies and quantifies low-boiling residual solvents or degradation products via thermal desorption and mass spectral detection. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Measures hydrogen ion activity in 10% w/w aqueous dispersion using calibrated glass electrode. |
| Appearance | Visual Inspection | Assesses physical state, clarity, and presence of undissolved particles or phase separation under controlled lighting. |
