Description

Allyloxy-T-Butyldimethylsilane CAS NO 105875-75-0 is a versatile organosilicon reagent featuring both an allyl ether and a tert-butyldimethylsilyl (TBDMS) protecting group. This bifunctional compound is valued for its role as a key synthetic intermediate and protecting group precursor in advanced organic synthesis. It is primarily sought after by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty chemical industries for constructing complex molecular architectures.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and complex drug candidates, particularly where silicon-containing moieties or specific ether linkages are required.
• Agrochemical Synthesis: Serves as a building block for creating novel pesticides, herbicides, and plant growth regulators with enhanced properties.
• Polymer & Material Science: Acts as a monomer or cross-linking agent in the production of specialty silicones, siloxane-based polymers, and advanced materials with tailored surface properties.
• Protecting Group Chemistry: The TBDMS group is a cornerstone for protecting alcohols in multi-step syntheses, while the allyloxy moiety can be further functionalized.
• Organic Synthesis Reagent: Employed in palladium-catalyzed cross-coupling reactions (e.g., Heck, Sonogashira) and other transition metal-mediated transformations due to the reactive allyl group.
• Liquid Crystal & Electronic Chemicals: Used in the research and development of organic semiconductors, liquid crystal display (LCD) materials, and other electronic-grade chemicals.

Quality Control

Our Allyloxy-T-Butyldimethylsilane is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including GC, NMR, and Karl Fischer titration, to ensure high purity and consistency. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to guarantee supply reliability and product traceability for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area 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 product loss.
