Industrial Applications of 1-Trimethylsilyl-1-butyne
| Industry | Application | Process |
|---|---|---|
| Organic Synthesis | As an alkynylation reagent or precursor for protecting groups | Participates in Sonogashira coupling reactions under palladium or copper catalysis to construct carbon–carbon triple bonds; the trimethylsilyl group serves as a protecting group for terminal alkynes and is removed with fluoride ions (e.g., TBAF) in subsequent steps to generate free terminal alkynes |
| Pharmaceutical R&D | Intermediate for active pharmaceutical ingredient (API) synthesis | Used to construct alkyne-containing heterocyclic or acyclic molecular scaffolds, commonly featured in synthetic routes to kinase inhibitors, antitumor agents, or antiviral compounds |
| Materials Science | Monomer for conjugated polymer or functional material synthesis | Engages in click chemistry or Glaser coupling reactions to prepare polymers with optoelectronic properties or precursors for metal–organic frameworks (MOFs) |
| Agricultural Chemicals | Intermediate for novel pesticide synthesis | Serves as an alkyne-introducing unit to construct molecular structures with specific biological activity, such as lead compounds for fungicides or herbicides |
Manufacturing Quality Control of 1-Trimethylsilyl-1-butyne
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component by retention time and peak area against calibrated standard. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric reaction between iodine and water 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 with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Heavy Metals (Pb, Cd, Hg, Cr) | ICP-OES | Atomizes and excites sample in plasma; measures element-specific emission intensities. |
| Color | Visual Comparison to Hazen Scale | Compares sample color against platinum-cobalt standard solutions in Nessler tubes under controlled lighting. |
| Density at 20 C | Digital Density Meter | Measures mass per unit volume using oscillating U-tube principle with temperature control. |
| Refractive Index at 20 C | Refractometry | Determines ratio of light velocity in air vs. sample using critical angle measurement. |
| Boiling Point Range | Distillation (Micro or Semi-micro) | Measures temperature interval over which 90% of sample distills under reduced pressure. |
| Non-Volatile Residue (by GC) | Gas Chromatography with TCD | Detects and estimates high-boiling or thermally unstable residues not eluted under standard GC conditions. |
| Odor Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies volatile odor-causing impurities by mass spectral library matching and retention index. |
