Manufacturing Quality Control of 2157-45-1
| 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 internal or external standard. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Acidity (as HCl) | Acid-Base Titration with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color | Visual Comparison or Hazen (APHA) Scale | Compares sample color against platinum-cobalt standard solutions under controlled lighting. |
| Density at 20 C | Digital Density Meter | Determines mass per unit volume using oscillating U-tube principle with temperature control. |
| Refractive Index at 20 C | Refractometry | Measures bending of light through liquid sample at specified wavelength (e.g., sodium D line). |
| Residue on Evaporation | Gravimetric Analysis | Evaporates known sample mass under controlled conditions and weighs non-volatile residue. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride anions using conductivity detection after ion exchange separation. |
| Heavy Metals (as Pb) | ICP-OES | Atomizes and excites sample in plasma; measures characteristic emission intensities for metal elements. |
| Iron Content | ICP-OES | Same principle as heavy metals; uses specific Fe emission lines for quantitative determination. |
| Ethoxy Group Content | Hydrolysis followed by GC or Titration | Cleaves alkoxy groups via acid-catalyzed hydrolysis, then quantifies released alcohol or acid. |
| Volatile Impurities | Headspace Gas Chromatography (HS-GC) | Analyzes low-boiling impurities in vapor phase above sample at controlled temperature. |
