Industrial Applications of 17985-72-7
| Industry | Application | Process |
|---|---|---|
| Organic Synthesis / Chemical Feedstocks | Key intermediate for synthesizing polycyclic aromatic hydrocarbons or silacyclic compounds | Serves as a coupling precursor to construct silacyclic frameworks via intramolecular bimetalation |
| Pharmaceutical R&D | Synthesis of biologically active silicon-containing drug molecules or drug candidates | Introduces silyl groups or forms carbon–carbon bonds via coupling reactions (e.g., Hiyama coupling) |
| Research / Academic Studies | Model compound for studying transition-metal-catalyzed reaction mechanisms and silicon chemistry | Investigates transition-metal (e.g., palladium, platinum)-catalyzed C–H bond activation and Si–C bond transformations |
| Materials Science | Production of high-performance organosilicon polymers or specialty functional materials | Ring-opening polymerization or copolymerization to incorporate silyl groups into polymer backbones or side chains |
Manufacturing Quality Control of 17985-72-7
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component peak area against calibrated standard; separation based on volatility and polarity. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatilized solvents are extracted in headspace vial and quantified by GC-FID or GC-MS. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine reacts stoichiometrically with water; endpoint detected amperometrically. |
| Acid Number | Acid-Base Titration with Potentiometric Detection | Neutralization of acidic impurities using standardized KOH in isopropanol; endpoint determined by pH change. |
| Chloride Content | Ion Chromatography (IC) | Separation of chloride anions on ion-exchange column followed by conductivity detection. |
| Heavy Metals (Pb, Cd, Hg, Cr) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Sample digested to solution, then atomized and excited in plasma; element-specific emission intensities measured. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Sample heated at 700-800 C to volatilize organics; inorganic residue weighed after cooling. |
| Color | APHA Color Scale (Visual or Spectrophotometric) | Comparison of sample color to platinum-cobalt standard solutions using visual matching or spectrophotometric absorbance at 455 nm. |
| Density | Oscillating U-tube Densitometry | Measures resonant frequency shift of a vibrating U-shaped tube filled with sample; related to density via calibration. |
| Refractive Index | Refractometry (Abbe Refractometer) | Determines refractive index based on critical angle of total internal reflection at prism-sample interface. |
| Viscosity | Capillary Viscometry (Ubbelohde) | Measures flow time of fixed volume through calibrated capillary under gravity; kinematic viscosity calculated from time and calibration constant. |
| Non-Volatile Residue | Evaporation Residue Test (Gravimetric) | Sample evaporated to dryness under controlled temperature and airflow; residue weighed as percentage of original mass. |
