Industrial Applications of 20515-15-5
| Industry | Application | Process |
|---|---|---|
| Fine Fragrances & Flavors | Used as a synthetic fragrance intermediate in formulating fruit- and flower-type fragrances | Participates in fragrance molecule construction via esterification or condensation reactions |
| Pharmaceuticals | Used as an organic synthesis intermediate in constructing certain drug molecules | Serves as a carbon-chain extension or functional-group introduction unit in multistep syntheses |
| Agrochemicals | Used as an intermediate in synthesizing agrochemical active ingredients (e.g., pheromones, plant growth regulators) | Converted into target compounds through organic transformations such as Wittig reactions, reductions, or oxidations |
| Fine Chemicals | Used in synthesizing fine chemicals with specific odors or biological activity | Acts as an α,β-unsaturated ester in reactions including Michael addition and Diels–Alder cycloaddition |
Manufacturing Quality Control of 20515-15-5
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component peak area relative to calibration curve using internal or external standard. |
| Related Substances | Gas Chromatography (GC) with FID detection | Identifies and quantifies impurities by retention time comparison and peak area integration. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Acid Value | Acid-Base Titration with NaOH standard solution | Determines free acid content by titration with standardized sodium hydroxide using phenolphthalein indicator. |
| Ester Content | Hydrolysis followed by GC analysis | Cleaves ester bond under controlled alkaline conditions; quantifies liberated alcohol or acid derivative by GC. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and weighing. |
| Heavy Metals | ICP-OES | Quantifies trace metal elements (e.g., Pb, Cd, Hg, As) by plasma excitation and elemental emission intensity measurement. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions based on anion exchange retention and conductivity detection. |
| Refractive Index | Refractometry | Measures bending of light through liquid sample at specified temperature to assess purity and concentration. |
| Specific Gravity | Pycnometry | Determines density ratio relative to water using calibrated glass pycnometer at controlled temperature. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Evaluates yellowness intensity by matching sample color to APHA platinum-cobalt standard scale. |
| Boiling Range | Distillation with Temperature Monitoring | Determines temperature interval over which 90% of sample distills under specified pressure and rate conditions. |
