Manufacturing Quality Control of 2,3,4,5-TETRAMETHYL-2-CYCLOPENTENONE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component peak area relative to calibration curve using internal or external standard. |
| Related Substances | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and semi-quantifies impurities based on retention time and mass spectral fragmentation patterns. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Measures water via electrochemical reaction between iodine, sulfur dioxide, and water in anhydrous methanol medium. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Determines non-volatile inorganic residue after high-temperature ashing at 700-800 C. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after acid digestion by measuring absorbance of ground-state atoms in flame. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions using conductivity detection after aqueous extraction. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement | Compares sample color intensity against platinum-cobalt standard solutions at 430 nm. |
| Density at 20 C | Oscillating U-tube Densitometry | Determines density from resonant frequency shift of a vibrating U-shaped glass tube filled with sample. |
| Refractive Index at 20 C | Refractometry (Abbe type) | Measures refractive index based on critical angle of total internal reflection at prism-sample interface. |
| Boiling Point Range | Capillary Boiling Point Apparatus | Determines temperature interval over which sample distills under reduced pressure (e.g., 10 mmHg). |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Quantifies volatile organic solvents by equilibrium partitioning into headspace followed by GC-FID analysis. |
