Industrial Applications of TERT-BUTYLDIMETHYL(2-PROPYNYLOXY)SILANE
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates | Used as a propargyl hydroxyl protecting group for selective protection and deprotection in multistep synthesis | Introduced under basic conditions (e.g., n-BuLi) via reaction with alcohols; deprotection typically performed using fluoride reagents (e.g., TBAF) or acidic conditions |
| Organic Synthesis | Employed as a silyl protecting reagent to stabilize propargylic alcohol substrates and suppress side reactions | Silylation carried out under anhydrous, oxygen-free conditions, reacting with propargylic alcohols in an imidazole/DMF system |
| Materials Science | Applied to modify alkyne-functionalized surfaces, enabling preparation of silyl-based interfacial materials with tailored reactivity | Reacted with surface hydroxyl groups to deposit a propargyloxy silane layer on silicon wafers or glass substrates, enabling subsequent click chemistry grafting |
Manufacturing Quality Control of TERT-BUTYLDIMETHYL(2-PROPYNYLOXY)SILANE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | GC-FID | Quantification by gas chromatography with flame ionization detection using an internal standard and calibration curve. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents based on retention time and peak area comparison. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric titration where iodine reacts stoichiometrically with water in a controlled electrochemical or chemical system. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride ions using anion-exchange column and conductivity detection. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element detection via inductively coupled plasma mass spectrometry after acid digestion and dilution. |
| Residual Catalyst (Pd, Pt) | ICP-OES | Elemental quantification by measuring atomic emission intensities from plasma-excited atoms. |
| Acid Value | Acid-Base Titration | Neutralization of acidic impurities with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Assessment of yellowness/browning by comparing sample color to platinum-cobalt standard solutions or measuring absorbance at 430 nm. |
| Density | Digital Density Meter | Measurement of mass per unit volume at specified temperature using oscillating U-tube principle. |
| Refractive Index | Refractometry | Determination of light bending angle at air-sample interface using calibrated prism-based instrument. |
| Peroxide Value | Iodometric Titration | Oxidation of iodide to iodine by peroxides, followed by titration with standardized sodium thiosulfate. |
| Volatile Impurities (Non-Solvent) | GC-MS | Identification and semi-quantification of low-boiling organic impurities via mass spectral library matching and peak integration. |
