Manufacturing Quality Control of EICOSANEDIOIC ACID DIMETHYL ESTER
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard using a non-polar capillary column. |
| Acid Value | Acid-Base Titration with KOH in ethanol | Neutralization of free carboxylic acid groups by standardized potassium hydroxide solution, detected by phenolphthalein endpoint. |
| Water Content | Karl Fischer Coulometric Titration | Electrochemical generation and reaction of iodine with water in anhydrous methanol-based reagent; water quantified via coulometric current integration. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 455 nm | Comparison of sample solution color intensity to APHA platinum-cobalt standards or absorbance measurement at specified wavelength. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Heating to 700-800 C in a muffle furnace followed by weighing of non-volatile inorganic residue. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) after wet digestion | Sample decomposition with nitric/hydrochloric acid mixture, followed by quantitative measurement of metal absorption at characteristic wavelengths. |
| Chloride Content | Potentiometric Titration with AgNO3 | Precipitation of chloride as AgCl monitored by silver ion-selective electrode; endpoint determined from potential inflection. |
| Refractive Index | Refractometry at 20 C | Measurement of light bending angle through liquid sample relative to air, correlated to molecular composition and purity. |
| Specific Gravity | Digital Density Meter or Pycnometer Method | Ratio of sample density to water density at specified temperature, reflecting bulk compositional consistency. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as solid-to-liquid phase change; indicates crystallinity and presence of impurities. |
| Residual Solvents (e.g., MeOH, DCM) | Headspace Gas Chromatography (HS-GC) with FID | Volatile solvent quantification via equilibrium vapor phase analysis above heated sample using calibrated GC method. |
| Non-Volatile Residue | Evaporation and Gravimetric Weighing | Solvent evaporation under controlled conditions followed by mass measurement of residual solids. |
