Description

1,3-Bis(4-Biphenyl)-1,1,3,3-Tetramethyldisilazane, 95% is a high-purity organosilicon compound featuring a disilazane core flanked by biphenyl groups. This chemical matters as a versatile intermediate and precursor, particularly valued in advanced materials science for its role in modifying surfaces and synthesizing complex silicon-containing polymers. It is primarily needed by R&D laboratories and manufacturers in the electronics, semiconductor, and specialty polymer industries for applications requiring precise molecular architecture and controlled reactivity.

Application

• Advanced Material Synthesis: Acts as a key monomer or cross-linking agent in the production of high-performance siloxane polymers and resins.
• Surface Modification & Functionalization: Used as a silylating agent to impart hydrophobic or specific functional properties to inorganic surfaces like silica, glass, or metals.
• Semiconductor & Electronics Manufacturing: Serves as a precursor for thin-film deposition (e.g., via Chemical Vapor Deposition) and in the fabrication of low-k dielectric materials.
• Pharmaceutical & Agrochemical Intermediates: Utilized in the synthesis of complex molecules where the disilazane group acts as a protecting group or a directing moiety.
• Catalysis & Ligand Design: Employed in the development of novel organometallic catalysts and ligands for asymmetric synthesis.
• Adhesive & Sealant Formulations: Incorporated to enhance the thermal stability, adhesion, and mechanical properties of silicone-based products.

Quality Control

Our 1,3-Bis(4-Biphenyl)-1,1,3,3-Tetramethyldisilazane, 95% undergoes rigorous quality testing to ensure compliance with industry standards. Each batch is analyzed to confirm identity, purity, and consistency. Certificates of Analysis (COA) detailing specific test results are available upon request to support your quality assurance protocols.

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) to prevent degradation.
