Industrial Applications of (2-BROMOETHYNYL)TRIISOPROPYLSILANE
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Chemicals | Synthesis of pharmaceutical intermediates and active pharmaceutical ingredients (APIs) | Used as an alkynylation reagent or synthon to construct drug molecules containing alkyne moieties; participates in palladium-catalyzed Sonogashira coupling reactions to build complex arylalkyne structures. |
| Organic Synthesis | Protecting group chemistry | Employed as a triisopropylsilyl (TIPS) protecting group for hydroxyl groups or terminal alkyne protons, enabling selective functional group protection during multistep synthesis and subsequent deprotection to yield the target compound. |
| Materials Science | Synthesis of functional material monomers | Applied in the synthesis of conjugated polymers or organosilicon materials with tailored optoelectronic properties; silicon incorporation enhances solubility or modulates band-gap structure. |
| Organic Synthesis | Preparation of terminal alkynes | Serves as a masked acetylene equivalent to introduce acetylene functionality; terminal alkynes are generated via subsequent deprotection. |
Manufacturing Quality Control of (2-BROMOETHYNYL)TRIISOPROPYLSILANE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | GC-FID | Quantifies main component using flame ionization detection with calibrated reference standard. |
| Related Substances | GC-MS | Identifies and semi-quantifies impurities based on retention time and mass spectral matching. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., hexane, THF) using headspace or direct injection. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration with iodine-based reagent. |
| Acidity (as HBr) | Acid-Base Titration | Titration with standardized NaOH to quantify acidic impurities generating H+ in alcoholic medium. |
| Heavy Metals | ICP-OES | Simultaneously quantifies metals (e.g., Fe, Cu, Pb) after acid digestion using plasma optical emission. |
| Chloride Content | Ion Chromatography | Separates and quantifies Cl- anions using conductivity detection after aqueous extraction. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and weighing. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity against established reference standards under controlled lighting. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using calibrated capillary method. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light to confirm chiral integrity and identity. |
| Bulk Density | Tap Density Measurement | Determines mass per unit volume after standardized mechanical tapping of a powder sample. |
