Description

Beta β-Bis(Trimethylsilyloxy)-Styrene CAS NO 31491-21-1 is a specialized organosilicon compound featuring a styrene backbone protected by trimethylsilyloxy groups. This unique structure makes it a valuable protected intermediate and monomer in advanced organic synthesis and polymer chemistry. It is primarily sought after by R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty polymer industries for constructing complex molecules and functional materials.

Application

• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly where the protected diol functionality is required.
• Agrochemical Synthesis: Used in the development of novel pesticides and herbicides, leveraging its reactivity to introduce specific functional groups.
• Specialty Polymer Monomer: Acts as a monomer or co-monomer for creating polymers with tailored properties such as modified surface characteristics, hydrophobicity, or specific degradation profiles.
• Material Science Research: Employed in the development of advanced organic-inorganic hybrid materials, coatings, and resins.
• Cross-coupling Reactions: Utilized in palladium-catalyzed and other metal-mediated coupling reactions to form new carbon-carbon bonds.
• Protecting Group Chemistry: The trimethylsilyloxy groups act as protecting groups for diols, which can be selectively removed under mild conditions.

Quality Control

Our Beta β-Bis(Trimethylsilyloxy)-Styrene is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory needs.

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 nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and degradation.
