Manufacturing Quality Control of propanoic acid, 3-hydroxy-, ethyl ester
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies 3-hydroxypropionic acid ethyl ester by retention time and peak area against a calibrated standard. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Determines acidic impurities by titration with standardized sodium hydroxide using phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 430 nm | Evaluates yellowness by comparing sample absorbance at 430 nm to APHA platinum-cobalt standards. |
| Density at 20 degC | Digital Density Meter (Oscillating U-tube) | Measures mass per unit volume based on resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index at 20 degC | Refractometry | Determines refractive index by measuring angle of light refraction at air-sample interface using calibrated prism. |
| Residue on Evaporation | Gravimetric Analysis | Quantifies non-volatile residue after controlled evaporation and drying, followed by weighing. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Measures total heavy metals after wet digestion by quantifying lead absorption at characteristic wavelength. |
| Chloride Content | Ion Chromatography (IC) or Potentiometric Titration | Detects chloride ions via separation and conductivity detection (IC) or silver nitrate titration with chloride-selective electrode. |
| Aldehyde Impurities (e.g., Acetaldehyde) | Gas Chromatography (GC) with FID or HS-GC | Separates and quantifies volatile aldehydes using headspace sampling and flame ionization detection. |
| Residual Ethanol | Gas Chromatography (GC) with FID | Quantifies residual ethanol by chromatographic separation and peak area comparison to ethanol standard. |
| Peroxide Value | Iodometric Titration | Measures peroxides by oxidation of iodide to iodine under acidic conditions, followed by thiosulfate titration. |
