Manufacturing Quality Control of Dimethyl propylmalonate
| 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 calibrated column and carrier gas. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based solvent system. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 430 nm | Comparison of sample color to platinum-cobalt standard solutions or absorbance measurement at specified wavelength. |
| Density at 20 degC | Digital Density Meter (Oscillating U-tube) | Measurement of sample density via oscillation frequency shift of a U-shaped glass tube filled with the sample. |
| Refractive Index at 20 degC | Abbe Refractometer | Determination of refractive index by measuring the critical angle of total internal reflection at the prism-sample interface. |
| Residue on Evaporation | Gravimetric Analysis | Evaporation of a known volume under controlled conditions followed by weighing of non-volatile residue. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of metal content after acid digestion and atomization, based on absorption of element-specific wavelengths. |
| Chloride Content | Potentiometric Titration with AgNO3 | Titration with silver nitrate using a silver electrode to detect endpoint via potential change from AgCl precipitation. |
| Ester Content (by saponification value) | Saponification Titration with KOH | Hydrolysis of ester groups with excess potassium hydroxide, followed by back-titration of unreacted alkali. |
| Non-Volatile Residue | Gravimetric Analysis after Solvent Evaporation | Evaporation of solvent under vacuum at defined temperature, then drying and weighing of residual solids. |
| Organic Impurities (Related Substances) | Gas Chromatography-Mass Spectrometry (GC-MS) | Separation by GC followed by identification and quantification of impurities using mass spectral fragmentation patterns. |
