Manufacturing Quality Control of 2,4-OCTADIENAL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies 2,4-octadienal peak area relative to internal/external standard using calibrated response factors. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration based on iodine consumption in pyridine-methanol medium. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 430 nm | Compares sample color to platinum-cobalt standard solutions or measures absorbance at 430 nm. |
| Refractive Index | Refractometry at 20 C | Determines refractive index using a calibrated Abbe refractometer at controlled temperature. |
| Density | Digital Density Meter or Pycnometer | Measures mass per unit volume at specified temperature (e.g., 20 C) using oscillating U-tube or calibrated flask. |
| Residue on Evaporation | Gravimetric Analysis | Evaporates known volume under controlled conditions and weighs non-volatile residue after drying. |
| Aldehyde Content (by Hydroxylamine Hydrochloride) | Spectrophotometric Determination (UV-Vis at ~360 nm) | Measures oxime formation product absorbance; proportional to aldehyde concentration. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after acid digestion by measuring atomic absorption at characteristic wavelengths. |
| Residual Solvents (e.g., Hexane, Ethanol) | Gas Chromatography (GC) with Headspace Sampling | Separates and quantifies volatile solvents using headspace injection and FID detection. |
| Peroxide Value | Iodometric Titration | Measures peroxides by iodide oxidation to iodine, followed by sodium thiosulfate titration. |
| Odor Profile | Gas Chromatography-Olfactometry (GC-O) or Sensory Panel | Combines GC separation with human detection threshold assessment or trained panel evaluation. |
