Manufacturing Quality Control of Oxalic acid 1-ethyl ester
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component by retention time and peak area against certified reference standard. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, and sulfur dioxide in pyridine/methanol medium. |
| Acidity (as H2C2O4) | Acid-Base Titration with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic residue after high-temperature ashing and weighing. |
| Color | Visual Comparison or Spectrophotometry (APHA scale) | Compares sample color to platinum-cobalt standard solutions using visual or UV-Vis absorbance at 455 nm. |
| Density | Digital Density Meter | Measures mass per unit volume at specified temperature using oscillating U-tube principle. |
| Refractive Index | Refractometry | Determines ratio of light velocity in air vs. sample using critical angle measurement at 20 C. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions based on anion exchange and conductivity detection. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Measures total heavy metals after wet digestion by atomic absorption at characteristic wavelength. |
| Non-Volatile Residue | Gravimetric Analysis | Weighs residue remaining after evaporation of sample under controlled heating and drying conditions. |
| Ethanol Content | Gas Chromatography (GC) with FID | Quantifies residual ethanol using internal standard and calibrated GC response. |
| Appearance | Visual Inspection | Assesses clarity and absence of visible particles or phase separation in a clear glass container under controlled lighting. |
