Industrial Applications of tert-Butyldimethyl(4-pentynyloxy)silane
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Used as a key intermediate in synthesizing alkyne-containing targeted drug molecules, such as kinase inhibitors and PROTAC degraders | Acts as an alkyne donor in palladium-catalyzed cross-coupling reactions (e.g., Sonogashira coupling); the TBS protecting group can be selectively removed under mild acidic conditions |
| Organic Synthesis | Used to construct alkyne structural motifs in complex natural products and functional materials | Serves as a precursor to propargylic alcohol derivatives; after TBS protection, it participates in multistep transformations—including cyclization and addition—enhancing regioselectivity and functional group compatibility |
| Materials Science | Used to prepare alkyne-containing organic optoelectronic material monomers, such as conjugated polymers and metal–organic framework (MOF) ligands | Undergoes click chemistry (CuAAC) with azides to introduce functional side chains; the TBS group provides steric bulk to modulate polymer chain conformation |
Manufacturing Quality Control of tert-Butyldimethyl(4-pentynyloxy)silane
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component by retention time and peak area relative to calibrated standard. |
| Related Substances | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and semi-quantifies impurities based on retention time and characteristic mass fragments. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Measures volatile organic solvents using equilibrium vapor phase analysis. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Determines water via electrochemical iodine generation and stoichiometric reaction with water. |
| Acidity (as HCl) | Acid-Base Titration with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution and potentiometric endpoint detection. |
| Heavy Metals | Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) | Quantifies trace metal elements (e.g., Pb, Cd, Ni) by atomic emission intensity at element-specific wavelengths. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Measures non-volatile inorganic residue after controlled high-temperature ashing. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light caused by chiral centers in solution. |
| Refractive Index | Refractometry | Determines refractive index at specified temperature using Snell's law-based optical measurement. |
| Boiling Point | Capillary Boiling Point Apparatus | Determines temperature at which vapor pressure equals atmospheric pressure under reduced pressure conditions. |
| Appearance and Color | Visual Inspection against Standard Color Scales (e.g., APHA) | Assesses physical state, clarity, and color by comparison to platinum-cobalt reference standards. |
