Industrial Applications of (TRIETHYLSILYL)ACETYLENE
| Industry | Application | Process |
|---|---|---|
| Organic Synthesis | Used as an alkynyl protecting group for selective carbon–carbon bond formation | Deprotonated under basic conditions (e.g., n-BuLi), then added to aldehydes/ketones, or employed in Sonogashira coupling; the TES group is subsequently removed under mild conditions using fluoride (e.g., TBAF) |
| Pharmaceutical R&D | Used in the synthesis of bioactive molecules and drug intermediates containing alkyne moieties | Serves as a key building block to introduce terminal alkynes, enabling conjugation of targeting groups or fluorescent labels via Cu(I)-catalyzed azide–alkyne cycloaddition (CuAAC) |
| Materials Science | Used to prepare conjugated polymers and organic semiconductor materials | Employed in Stille, Suzuki, or Sonogashira cross-coupling reactions to construct π-conjugated backbones for OLED and OFET devices |
| Agrochemical Chemistry | Used to synthesize novel agrochemically active compounds containing silyl-alkyne structures | Functions as a functionalized intermediate to introduce silyl groups, thereby modulating lipophilicity and metabolic stability, and participates in multi-step functional group transformations |
Manufacturing Quality Control of (TRIETHYLSILYL)ACETYLENE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) | Quantifies main component by separation and peak area comparison against calibrated standard. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, and sulfur dioxide in pyridine/methanol medium. |
| Residue on Evaporation | Gravimetric Analysis | Determines non-volatile impurities by evaporating sample under controlled conditions and weighing residue. |
| Acidity (as HCl) | Acid-Base Titration | Titration with standardized NaOH using phenolphthalein indicator to quantify acidic impurities. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions based on ion exchange and conductivity detection. |
| Heavy Metals (Pb, Cd, Hg, As) | Inductively Coupled Plasma - Optical Emission Spectrometry (ICP-OES) | Atomizes sample and measures element-specific emission intensities for multi-element trace metal analysis. |
| Color | Visual Comparison or Colorimeter | Evaluates hue and intensity against platinum-cobalt (APHA) standard scale. |
| Density | Digital Density Meter | Measures mass per unit volume at specified temperature using oscillating U-tube principle. |
| Refractive Index | Refractometry | Determines ratio of light velocity in air vs. sample using critical angle measurement at 20 C. |
| Volatile Impurities | Headspace Gas Chromatography-Mass Spectrometry (HS-GC-MS) | Extracts and identifies low-boiling contaminants via thermal equilibrium and mass spectral detection. |
| Peroxide Value | Iodometric Titration | Quantifies peroxides by oxidation of iodide to iodine, followed by titration with sodium thiosulfate. |
| Non-Volatile Alkali (Na, K) | Flame Photometry | Measures alkali metal emission intensities in flame for semi-quantitative determination. |
