Manufacturing Quality Control of 2-CHLOROMALONALDEHYDE
| 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. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine is generated in situ to react stoichiometrically with water; endpoint detected amperometrically. |
| Residual Solvents | Gas Chromatography (GC) with Headspace sampling | Separation and quantification of volatile organic impurities using headspace equilibrium followed by GC-FID analysis. |
| Chloride Ion Impurity | Ion Chromatography (IC) with conductivity detection | Anion exchange separation followed by quantitative detection of Cl- based on electrical conductivity response. |
| Acidity (as HCl) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and potentiometric or indicator-based endpoint detection. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element quantification after acid digestion, based on mass-to-charge ratio detection with high sensitivity and low detection limits. |
| Aldehyde Content | UV-Vis Spectrophotometry (after derivatization with DNPH) | Formation of hydrazone derivative with 2,4-dinitrophenylhydrazine, followed by absorbance measurement at ~360 nm. |
| Color | APHA Color Scale (Visual or Instrumental) | Comparison of sample color intensity against platinum-cobalt standard solutions using spectrophotometric or visual matching. |
| Density | Digital Density Meter (Oscillating U-tube) | Measurement of sample density via resonant frequency shift of a vibrating U-shaped tube filled with the liquid. |
| Refractive Index | Abbe Refractometer | Determination of refractive index at 20 C using critical angle measurement of light passing through the sample-prism interface. |
| Non-Volatile Residue | Gravimetric Analysis (Evaporation and Weighing) | Evaporation of a known volume under controlled conditions followed by drying and weighing of residual solids. |
| Related Substances | HPLC with UV detection | Separation and quantification of structurally related impurities using reversed-phase C18 column and UV detection at 220 nm. |
