Manufacturing Quality Control of Diethyl isopropylmalonate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantitative determination based on peak area comparison against a certified reference standard using a calibrated column and optimized temperature program. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water; endpoint detected by current change. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution, with potentiometric or phenolphthalein endpoint detection. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Sample heated to 700–800 °C; non-volatile residue mass measured after cooling in desiccator. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS or ICP-OES | Multi-element quantification after acid digestion; detection based on element-specific atomic emission (ICP-OES) or mass-to-charge ratio (ICP-MS). |
| Chloride Impurity | Ion Chromatography (IC) with Conductivity Detection | Separation of anions on ion-exchange column; chloride quantified via conductivity response relative to calibration standards. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 455 nm | Comparison of sample color intensity against platinum-cobalt standard solutions or absorbance measurement at specified wavelength. |
| Density at 20 °C | Digital Density Meter (Oscillating U-tube principle) | Measurement of sample density based on resonant frequency shift of a vibrating U-shaped tube filled with the liquid. |
| Refractive Index at 20 °C | Digital Refractometer | Determination of refractive index via critical angle measurement of light passing through the sample-prism interface. |
| Non-Volatile Residue | Gravimetric Evaporation | Evaporation of a known volume under controlled conditions (e.g., 105 °C, N₂ stream), followed by weighing of residual solids. |
| Related Substances (Impurity Profile) | GC-MS or GC-FID with Capillary Column | Separation and identification/quantification of structurally related impurities (e.g., monoethyl ester, diethyl malonate, isopropanol) using retention time and spectral matching (GC-MS) or relative response factors (GC-FID). |
