Manufacturing Quality Control of 2-Methyl-1,3-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 coulometric or volumetric titration based on iodine consumption in pyridine-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 metal impurities (e.g., Pb, Cd, Fe) by measuring absorption of element-specific light wavelengths. |
| Chloride Content | Potentiometric Titration with AgNO3 | Detects chloride ions by silver nitrate titration using silver indicator electrode and endpoint potential shift. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Measures acidic impurities by neutralization with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement | Evaluates yellowness/brownness by matching sample color to APHA platinum-cobalt standard scale. |
| Melting Point | Capillary Melting Point Apparatus | Determines phase transition temperature range using controlled heating and optical observation. |
| Specific Optical Rotation | Polarimetry | Measures chiral purity by detecting rotation angle of plane-polarized light passing through sample solution. |
| Residual Solvents | Gas Chromatography (GC) with Headspace Sampling | Identifies and quantifies volatile organic solvents by equilibrium headspace analysis and FID detection. |
| Non-Volatile Residue | Gravimetric Evaporation | Determines residue after evaporation of a defined sample volume under controlled temperature and vacuum. |
| Appearance (Clarity and Color) | Visual Inspection | Assesses physical state, clarity, and presence of particulates or discoloration against specified criteria. |
