Manufacturing Quality Control of Dimethyl methylmalonate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID | Quantitative separation and detection based on volatility and thermal conductivity differences; peak area comparison against reference standard. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based solvent system. |
| Acidity (as HCl) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color | APHA Color Scale (Visual or Spectrophotometric) | Comparison of sample color intensity to platinum-cobalt standard solutions using visual assessment or spectrophotometric absorbance at 430 nm. |
| Density at 20 C | Digital Density Meter | Measurement of mass per unit volume using oscillating U-tube principle calibrated with air and water standards. |
| Refractive Index at 20 C | Refractometry | Determination of light bending angle at air-sample interface using calibrated Abbe refractometer or digital equivalent. |
| Residue on Evaporation | Gravimetric Analysis | Evaporation of known sample mass under controlled temperature, followed by weighing of non-volatile residue. |
| Chloride Content | Ion Chromatography (IC) | Separation of chloride anions on ion-exchange column with conductivity detection and quantification against calibration curve. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Atomization of sample in flame or graphite furnace followed by measurement of absorption at characteristic wavelength for lead. |
| Residual Solvents (e.g., Methanol) | Gas Chromatography (GC) with FID | Separation and quantification of volatile solvents using headspace or direct injection GC with internal standard calibration. |
| Acid Number | Potentiometric Titration with KOH | Titration with standardized potassium hydroxide ethanol solution; endpoint detected by pH electrode potential shift. |
| Appearance | Visual Inspection | Assessment of clarity and presence of suspended particles or phase separation against specified criteria in transparent container under controlled lighting. |
