Manufacturing Quality Control of TRANS-2-METHYL-2-BUTENAL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID | Quantifies main component by separation and flame ionization detection relative to internal/external standard. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between iodine, sulfur dioxide, and water in pyridine/methanol medium. |
| Acidity (as Acetic Acid) | Acid-Base Titration | Determines acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Evaluates yellowness by matching sample color to APHA platinum-cobalt standard scale under controlled lighting. |
| Density at 20 C | Digital Density Meter | Measures mass per unit volume using oscillating U-tube principle calibrated with air and water. |
| Refractive Index at 20 C | Abbe Refractometer | Determines refractive index based on critical angle of total internal reflection at sample-prism interface. |
| Residue on Evaporation | Gravimetric Analysis | Weighs non-volatile residue after controlled evaporation of specified sample volume under nitrogen stream. |
| Aldehyde Content | Hydroxylamine Hydrochloride Titration | Quantifies aldehyde group via oxime formation followed by back-titration of unreacted hydroxylamine. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Detects trace metals by measuring absorption of characteristic wavelength light by ground-state atoms in flame. |
| Non-Volatile Matter | Gravimetric Analysis | Determines insoluble residue after filtration and drying of sample dissolved in suitable solvent. |
| Boiling Range | Distillation (ASTM D1078) | Measures temperature interval over which 90% of sample distills under controlled atmospheric pressure. |
| Organic Impurities (Related Substances) | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and quantifies structural analogs and degradation products via retention time and mass spectral matching. |
