Manufacturing Quality Control of 3-Methyl-1,2-cyclopentanedione
| 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. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic impurities by weighing residue after high-temperature ashing. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) | Quantifies metals (e.g., Pb, Cd, Hg) by measuring absorption of specific wavelengths of light by ground-state atoms in flame or graphite furnace. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions based on differential migration in an electrolyte solution under electric field. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution with phenolphthalein endpoint detection. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 455 nm | Evaluates yellowness by comparing sample color to APHA platinum-cobalt standards or measuring absorbance at specified wavelength. |
| Specific Gravity | Digital Density Meter | Determines density relative to water at 20/20 deg C using oscillating U-tube principle. |
| Refractive Index | Refractometry | Measures bending of light passing through sample at 20 deg C to infer purity and composition. |
| Volatility Residue | Loss on Drying (LOD) | Quantifies volatile matter by weight loss after controlled heating under specified time and temperature. |
| Related Substances | High-Performance Liquid Chromatography (HPLC) with UV detection | Separates and detects structurally related impurities using reversed-phase column and UV absorbance at 210–280 nm. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after carbonization and treatment with sulfuric acid followed by incineration. |
