Description

Allyldimethylsilane is a highly reactive organosilicon compound characterized by its allyl and dimethylsilyl functional groups. This unique structure makes it a valuable intermediate for introducing silicon-containing moieties into organic molecules via hydrosilylation and other addition reactions. It is primarily sought by R&D chemists and process engineers in the pharmaceutical, agrochemical, and advanced materials sectors for synthesizing novel silicone polymers, surface modifiers, and specialty chemical building blocks.

Application

• Hydrosilylation Catalyst Research: A key monomer and model substrate for developing and testing new platinum, rhodium, and other transition metal catalysts.
• Specialty Silicone Synthesis: Serves as a reactive intermediate for creating custom silicone oils, resins, and elastomers with tailored properties for high-performance applications.
• Surface Modification Agent: Used to functionalize inorganic surfaces (e.g., silica, glass) with organic allyl groups, altering wettability and adhesion characteristics.
• Pharmaceutical & Agrochemical Intermediates: Employed in the synthesis of novel active ingredients and prodrugs where a silicon-based functional group is required.
• Crosslinking Agent: Acts as a reactive crosslinker in polymer systems to enhance thermal stability and mechanical strength.
• Adhesion Promoters: A component in formulations designed to improve the bond between organic polymers and inorganic substrates.

Quality Control

Every batch of Allyldimethylsilane is produced and tested under strict quality management protocols to ensure consistency and purity for demanding synthetic applications. Our products undergo rigorous quality testing, including GC analysis, to ensure compliance with industry standards. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and hygroscopic (moisture-sensitive) nature, this material should be stored under an inert atmosphere (nitrogen or argon) in a cool, dry, and well-ventilated area. Recommended storage temperature is 2-8°C to maximize shelf-life stability. Keep away from heat, sparks, and open flame.
