Description

Trimethyl-[(E)-2-Phenylethenyl]Silane is a specialized organosilicon compound featuring a vinylbenzene (styryl) group attached to a trimethylsilyl moiety. This structure makes it a valuable reagent in synthetic organic chemistry, particularly for introducing the silyl-protected styryl group into target molecules. It is primarily utilized by research chemists and process development scientists in the pharmaceutical, agrochemical, and advanced materials sectors for constructing complex molecular architectures, including intermediates for active ingredients and functional polymers.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of novel drug candidates, particularly those requiring styrene-derived scaffolds.
• Agrochemical Synthesis: Used in the preparation of advanced pesticide and herbicide intermediates that incorporate aromatic olefin functionalities.
• Material Science Research: Serves as a monomer or functionalization agent in the development of specialty silicones and silicon-containing polymers with tailored properties.
• Cross-Coupling Reactions: Acts as a substrate in palladium-catalyzed reactions, such as Heck or Stille couplings, for carbon-carbon bond formation.
• Organic Synthesis Reagent: Employed as a versatile reagent for the protection of alcohols or phenols via formation of silyl ethers under specific conditions, or as a styryl anion equivalent.
• Liquid Crystal & OLED Precursor: Used in the research and development of organic electronic materials due to its conjugated system and silicon center.

Quality Control

Our Trimethyl-[(E)-2-Phenylethenyl]Silane is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including GC, NMR, and HPLC, to ensure high chemical purity and isomeric integrity. A Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to guarantee reliable performance in your critical synthetic applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic and highly volatile nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and decomposition. Keep away from heat, sparks, and open flame.
