Description

Vinyl(Diphenylphosphinoethyl)Dimethylsilane is a specialized organosilicon compound featuring a vinyl group and a diphenylphosphinoethyl moiety, making it a versatile ligand and building block in advanced chemical synthesis. Its primary value lies in its dual functionality, serving as both a silicon-based precursor and a phosphine ligand for transition metal catalysis. This product is essential for researchers and manufacturers in the fine chemical, pharmaceutical, and advanced materials sectors who require high-purity intermediates for developing catalysts, functional polymers, and novel silicon-containing compounds.

Application

• Catalyst Ligand in Homogeneous Catalysis: Acts as a phosphine ligand for transition metals (e.g., Pd, Pt, Rh) in cross-coupling, hydrogenation, and hydrosilylation reactions.
• Precursor for Functional Silicones: Used in the synthesis of specialty silicone polymers and resins with pendant phosphine groups for material modification.
• Surface Modification Agent: Employed to functionalize silica or other inorganic surfaces via the reactive vinyl or silane groups for advanced composites.
• Intermediate in Pharmaceutical Research: Serves as a key building block for creating novel organosilicon-active pharmaceutical ingredients (APIs) or catalyst systems for asymmetric synthesis.
• Material Science Research: Utilized in developing novel hybrid organic-inorganic materials, metal-organic frameworks (MOFs), and sensors.

Quality Control

Our Vinyl(Diphenylphosphinoethyl)Dimethylsilane is manufactured under strict quality protocols to ensure batch-to-batch consistency and high purity for research and industrial applications. Each lot undergoes comprehensive analysis, including NMR, GC, and HPLC, to verify identity and purity. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at room temperature (15-25°C) in a cool, dry, well-ventilated area. Keep away from strong oxidizing agents. Due to its sensitivity, minimize exposure to air and moisture during handling.
