Description

Divinyltetramethyldisilane is a highly reactive organosilicon compound featuring a disilane backbone with vinyl and methyl substituents. This unique structure makes it a valuable precursor and building block in advanced materials synthesis, particularly for introducing silicon-vinyl functional groups. It is primarily utilized by R&D chemists and material scientists in the semiconductor, specialty polymer, and organometallic catalyst industries.

Application

• Silicon-Containing Polymer Synthesis: Key monomer for producing polysilanes, polysiloxanes, and other specialty polymers with tailored properties.
• Semiconductor & Electronics Manufacturing: Used as a precursor in chemical vapor deposition (CVD) and atomic layer deposition (ALD) processes for depositing silicon carbide (SiC) or silicon-containing thin films.
• Surface Modification & Coupling Agent: Functionalizes inorganic surfaces (e.g., silica, metals) to create organic-compatible interfaces for coatings and composites.
• Organometallic & Catalyst Research: Serves as a ligand or reagent in the development of novel silicon-based catalysts and metal complexes.
• Crosslinking Agent: Imparts crosslinking sites in silicone elastomers and resins, enhancing thermal and mechanical stability.
• Organic Synthesis Intermediate: Employed in hydrosilylation and other reactions to construct complex organosilicon molecules for pharmaceuticals and agrochemicals.

Quality Control

Our Divinyltetramethyldisilane is manufactured under strict quality protocols. Every batch undergoes rigorous analytical testing including GC, NMR, and Karl Fischer titration to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to support your quality assurance requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated place, ideally at 2-8°C or under refrigeration as specified. Keep away from heat, sparks, and open flames. For long-term storage, consider maintaining under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation.
