Manufacturing Quality Control of 2-Methyl-5-vinylpyridine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component by retention time and peak area comparison against certified reference standard. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Acidity (as H2SO4) | Acid-Base Titration with NaOH | Determines acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 455 nm | Evaluates yellowness intensity by matching sample color to APHA platinum-cobalt scale or measuring absorbance at 455 nm. |
| Density at 20 degC | Digital Density Meter | Measures mass per unit volume using oscillating U-tube principle calibrated with air and water standards. |
| Refractive Index at 20 degC | Refractometry | Determines ratio of light velocity in air vs. sample using critical angle measurement of monochromatic light. |
| Residue on Evaporation | Gravimetric Analysis | Quantifies non-volatile residue after controlled evaporation of a defined sample mass under specified temperature and vacuum. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Measures total heavy metal content after wet digestion by quantifying absorbance of ground-state atoms in flame or graphite furnace. |
| Chloride Content | Potentiometric Titration with AgNO3 | Detects chloride ions by titration with silver nitrate using silver indicator electrode and reference electrode. |
| Peroxide Value | Iodometric Titration | Quantifies peroxides via oxidation of iodide to iodine under acidic conditions, followed by thiosulfate titration. |
| Non-Volatile Matter | Gravimetric Analysis | Determines insoluble residue after filtration, drying, and weighing of sample dissolved in specified solvent. |
| Trace Organic Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and semi-quantifies volatile impurities based on retention time and characteristic mass fragmentation patterns. |
