Manufacturing Quality Control of ETHYL 3-ETHOXYBUT-2-ENOATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component by separation on capillary column and flame ionization detection relative to external standard. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Determines water via electrochemical iodine generation and stoichiometric reaction with sample water. |
| Acid Value | Acid-Base Titration (NaOH in ethanol, phenolphthalein indicator) | Measures free carboxylic acid groups by titration with standardized sodium hydroxide solution. |
| Residue on Ignition | Gravimetric Analysis (Sulfated Ash method) | Evaluates inorganic impurities by high-temperature incineration followed by weighing of residual ash. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) after wet digestion | Quantifies total heavy metals by atomization of digested sample and absorption measurement at characteristic wavelength. |
| Chloride Impurity | Ion Chromatography (IC) with conductivity detection | Separates and quantifies chloride anions using ion-exchange column and suppressed conductivity detection. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement (430 nm) | Assesses yellowness intensity by matching to APHA platinum-cobalt standard solutions or measuring absorbance at 430 nm. |
| Specific Optical Rotation | Polarimetry | Determines chiral purity and enantiomeric excess by measuring rotation angle of plane-polarized light in solution. |
| Residual Solvents (e.g., EtOH, THF) | Headspace Gas Chromatography (HS-GC) with FID | Quantifies volatile organic solvents by equilibrium headspace sampling and GC separation with flame ionization detection. |
