Manufacturing Quality Control of 3-PENTEN-2-ONE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies 3-penten-2-one peak area relative to a calibrated standard using retention time and response factor. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration with iodine-based reagent reacting stoichiometrically with water. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color | APHA Color Scale (Visual or Spectrophotometric) | Compares sample color to platinum-cobalt standard solutions using visual matching or absorbance at 455 nm. |
| Density at 20 C | Digital Density Meter (Oscillating U-tube) | Determines density from resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index at 20 C | Refractometry | Measures bending of light passing through sample at specified temperature using calibrated prism instrument. |
| Residue on Evaporation | Gravimetric Analysis | Evaporates known volume under controlled conditions and weighs non-volatile residue after drying. |
| Aldehyde Impurities | Spectrophotometric DNPH Derivatization | Derivatizes aldehydes with 2,4-dinitrophenylhydrazine to form colored hydrazones measured at ~450 nm. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after wet digestion by measuring atomic absorption of ground-state metal atoms in flame. |
| Non-Volatile Residue | Gravimetric Analysis | Evaporates fixed mass under nitrogen stream at 105 C and weighs residual solids. |
| Peroxide Value | Iodometric Titration | Measures peroxides by oxidation of iodide to iodine in acidic medium, followed by sodium thiosulfate titration. |
| Specific Optical Rotation | Polarimetry | Determines rotation of plane-polarized light caused by chiral impurities or enantiomeric excess in solution. |
