| Industry | Application | Process |
|---|---|---|
| Chemical Synthesis | Organic synthesis intermediate | Used as a diene component in Diels–Alder reactions to construct six-membered ring systems, applied in the synthesis of natural products and pharmaceutical molecules |
| Pharmaceuticals | Drug development intermediate | Applied to introduce a butadiene backbone into complex molecular structures for synthesizing biologically active compounds |
| Materials Science | Functional material precursor | Used as a synthetic intermediate for preparing siloxy-functionalized polymers or specialty organosilicon materials |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component peak area relative to calibrated standard using retention time matching and response factor correction. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Measures volatile organic impurities by equilibrium partitioning into headspace followed by GC separation and FID detection. |
| Water Content | Karl Fischer Titration (Coulometric) | Determines water via electrochemical iodine generation proportional to sample water content in anhydrous methanol-based reagent. |
| Acid Value | Acid-Base Titration with NaOH standard solution | Measures acidic impurities by titration with standardized sodium hydroxide using phenolphthalein endpoint detection. |
| Residue on Ignition | Gravimetric Analysis after High-Temperature Ashing | Quantifies non-volatile inorganic residue by weight difference before and after ignition at 700-800 C in a muffle furnace. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Detects trace metal contaminants by atomization and excitation in plasma, measuring element-specific emission intensities. |
| Chloride Impurity | Ion Chromatography (IC) with Conductivity Detection | Separates and quantifies chloride ions based on anion exchange retention and conductivity response relative to calibration standards. |
| Refractive Index | Refractometry at 20 C | Measures bending of light through liquid sample to determine purity and consistency via correlation with known reference values. |
| Specific Gravity | Digital Density Meter (Oscillating U-tube) | Determines mass per unit volume by measuring resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 455 nm | Evaluates yellowness/browning intensity by comparing sample absorbance or visual match against platinum-cobalt standard solutions. |
| Volatile Impurities (Non-Solvent) | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and quantifies unknown volatile organic impurities using retention time and mass spectral library matching. |
| Silicon Content | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Quantifies total silicon by ionization in plasma and high-sensitivity mass filtering/detection of Si-28 or Si-29 isotopes. |
