Manufacturing Quality Control of METHYL 2-BUTYNOATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID | Quantitative separation and detection based on volatility and retention time using flame ionization detection. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based solvent system. |
| Acid Value | Acid-Base Titration with NaOH | Neutralization of free carboxylic acid groups using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color | APHA Color Scale (Visual or Spectrophotometric) | Comparison of sample color against platinum-cobalt standard solutions using visual assessment or absorbance at 455 nm. |
| Density | Digital Density Meter | Measurement of mass per unit volume at specified temperature (e.g., 20 C) using oscillating U-tube principle. |
| Refractive Index | Refractometry | Determination of light bending angle at air-sample interface using calibrated prism instrument at controlled temperature. |
| Residue on Evaporation | Gravimetric Analysis | Evaporation of known sample mass to dryness followed by weighing of non-volatile residue. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of metal ions after wet digestion, based on absorption of characteristic wavelength radiation by ground-state atoms. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and conductivity detection of chloride anions after aqueous extraction and filtration. |
| Residual Methanol | Gas Chromatography (GC) with FID | Direct injection and quantification of methanol peak relative to internal standard using thermal conductivity or FID detection. |
| Peroxide Value | Iodometric Titration | Oxidation of iodide to iodine by organic peroxides, followed by titration of liberated iodine with sodium thiosulfate. |
| Non-Volatile Matter | Gravimetric Analysis | Evaporation of sample under controlled conditions and weighing of residue after drying to constant weight. |
