Manufacturing Quality Control of 2-methylenepropane-1,3-diyl diacetate
| 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 Acetic Acid) | 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 controlled high-temperature ashing and weighing. |
| Color | Visual Comparison or Hazen Color Scale | Evaluates color intensity by comparing sample solution to platinum-cobalt standard solutions. |
| Specific Gravity | 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 versus sample using critical angle measurement. |
| Heavy Metals (as Pb) | ICP-OES | Quantifies trace metal elements by measuring characteristic atomic emission spectra after plasma atomization. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions based on anion exchange retention and conductivity detection. |
| Volatile Impurities | Headspace Gas Chromatography (HS-GC) | Detects low-boiling residual solvents by analyzing equilibrium vapor phase above heated sample. |
| Appearance | Visual Inspection | Assesses physical state, clarity, and presence of suspended particles or phase separation in undiluted sample. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube method. |
