Description

Bis(2-Methoxyphenyl)-1,1,2,2-Tetramethyldisilane, 95% CAS NO 332343-84-7 is a high-purity organosilicon compound featuring a central disilane core flanked by methoxyphenyl groups. This specific molecular architecture makes it a valuable synthetic intermediate and precursor in advanced materials chemistry. It is primarily utilized by R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty polymer industries for constructing complex silicon-containing frameworks.

Application

• Key Intermediate in Pharmaceutical Synthesis: Serves as a building block for novel active pharmaceutical ingredients (APIs), particularly in silicon-based drug discovery programs.
• Precursor for Advanced Materials: Used in the development of silicon-containing polymers, resins, and liquid crystals with tailored optical or electronic properties.
• Agrochemical Research: Employed in the synthesis of new-generation silicon-based pesticides and plant growth regulators.
• Cross-Coupling Reactions: Acts as a reagent in palladium-catalyzed cross-coupling reactions (e.g., Hiyama coupling) to form carbon-silicon or carbon-carbon bonds.
• Surface Modification Agent: Can be used to functionalize silica or other inorganic surfaces for specialized coatings and adhesives.
• Organic Light-Emitting Diode (OLED) Research: Investigated as a component in the synthesis of host or emitter materials for OLED devices.

Quality Control

Our Bis(2-Methoxyphenyl)-1,1,2,2-Tetramethyldisilane is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. Every lot is analyzed to confirm identity and assay specifications. Certificates of Analysis (COA) detailing purity, impurities, and other critical parameters are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
