Manufacturing Quality Control of DIMETHYLMALONONITRILE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative separation and detection based on volatility and retention time relative to a certified reference standard. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based solvent system. |
| Acidity (as HCN) | Acid-Base Titration with NaOH | Neutralization of acidic impurities (e.g., hydrocyanic acid) using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis | Heating sample to 700-800 C to volatilize organic matter, then weighing inorganic residue after cooling in desiccator. |
| Color | Visual Comparison Against APHA Scale | Comparison of sample color in solution to standardized platinum-cobalt reference solutions under controlled lighting. |
| Density at 20 C | Oscillating U-tube Densitometry | Measurement of sample density via resonant frequency shift of a vibrating U-shaped glass tube filled with the liquid. |
| Refractive Index at 20 C | Refractometry | Determination of refractive index by measuring angle of light refraction at air-sample interface using calibrated prism instrument. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of metal impurities after acid digestion by measuring absorbance of element-specific atomic vapor at characteristic wavelength. |
| Chloride Impurity | Ion Chromatography (IC) with Conductivity Detection | Separation of anions on ion-exchange column followed by quantitative detection based on electrical conductivity of eluted chloride ions. |
| Non-Volatile Residue | Evaporation and Gravimetry | Evaporation of fixed volume to dryness at 105 C, followed by weighing of residual solids after cooling. |
| Aldehyde Impurity | UV-Vis Spectrophotometry after Derivatization | Reaction with DNPH reagent forms hydrazone adduct with strong UV absorption; quantified via Beer-Lambert law. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution, indicating presence of chiral impurities or enantiomeric excess. |
