Description

Ethenyl-Tri(Propan-2-Yl)Silane CAS NO 121675-48-7 is a specialized organosilicon compound featuring a reactive ethenyl (vinyl) group and three bulky isopropyl substituents bonded to silicon. This unique structure makes it a valuable precursor and coupling agent in advanced material synthesis, offering controlled reactivity and steric influence. It is primarily utilized by R&D chemists and material scientists in the development of silicone polymers, surface-modifying agents, and inorganic-organic hybrid materials.

Application

• Silicone Polymer Modification: Acts as a functional monomer or cross-linking agent to introduce vinyl groups into silicone elastomers and resins, enhancing their cure properties and enabling further functionalization.
• Surface Functionalization: Used as a silylating agent to modify the surface of inorganic materials like silica, glass, or metals, imparting hydrophobic or reactive organic layers.
• Hybrid Material Synthesis: Serves as a key building block in sol-gel processes for creating organically modified silicates (ORMOSILs) with tailored mechanical and optical properties.
• Adhesion Promotion: Functions as a primer or additive in coatings and adhesives to improve bonding between organic polymers and inorganic substrates.
• Pharmaceutical & Agro-Intermediate: Employed in the synthesis of complex molecules where the silicon moiety acts as a protecting group or directs specific chemical transformations.
• Catalyst & Ligand Development: The sterically demanding isopropyl groups make it a candidate for constructing novel ligands in coordination chemistry and catalysis.

Quality Control

Our production of Ethenyl-Tri(Propan-2-Yl)Silane adheres to stringent internal quality protocols. Every batch undergoes comprehensive analysis using techniques including Gas Chromatography (GC) and NMR to ensure high chemical purity and identity confirmation. A detailed Certificate of Analysis (COA) providing batch-specific data is supplied with each shipment to guarantee traceability and compliance with your specifications.

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) to prevent moisture absorption and degradation.
