Manufacturing Quality Control of 3-methylcyclopent-2-en-1-one
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies 3-methyl-2-cyclopenten-1-one peak area relative to a calibration curve using an internal or external standard. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration based on the iodine-sulfur dioxide reaction in pyridine/methanol medium. |
| Acid Value | Acid-Base Titration with NaOH | Determines free acidic impurities by titrating with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometry at 455 nm | Compares sample color to APHA platinum-cobalt standards or measures absorbance at 455 nm in a 10-mm cell. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after controlled high-temperature ashing and weighing. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by atomization and absorption measurement at characteristic wavelengths after acid digestion. |
| Chloride Content | Potentiometric Titration with AgNO3 | Detects chloride ions via silver nitrate titration using a silver indicator electrode and reference electrode. |
| Refractive Index | Refractometry | Measures bending of light through liquid sample at 20 degrees C using a calibrated refractometer. |
| Specific Gravity | Pycnometry or Digital Density Meter | Determines ratio of sample density to water density at specified temperature using calibrated glass pycnometer or oscillating U-tube principle. |
| Non-Volatile Residue | Gravimetric Evaporation | Quantifies residue left after evaporating a known volume under controlled temperature and vacuum, then drying and weighing. |
| Aldehyde Impurities | HPLC with UV Detection | Separates and quantifies aldehyde-related impurities using reversed-phase column and UV absorbance at 210-280 nm. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Detects and quantifies volatile organic solvents by analyzing equilibrium vapor phase above heated sample. |
