Product Description:

Vinyltrimethylsilane is an organosilicon compound with the chemical formula CH2=CHSi(CH3)3. It is a colorless, flammable liquid characterized by a vinyl group attached to a trimethylsilyl group. This structure imparts unique reactivity and properties, making it a valuable monomer and synthetic building block. Its primary industrial application is as a key monomer in the synthesis of silicone polymers and copolymers. It is used to introduce vinyl functionality into polysiloxane chains, which is crucial for subsequent cross-linking reactions via hydrosilylation or peroxide curing. This makes it essential for producing high-performance silicone rubbers, resins, and release coatings. It also serves as a versatile reagent in organic synthesis, particularly for introducing the trimethylsilyl group or as a protected form of acetylene in certain transformations. The compound must be handled with care due to its flammability and potential irritant properties. It is typically stored under inert atmosphere to prevent polymerization and degradation.
