Description

Tetrakis(4-(4,4,5,5-Tetramethyl-1,3,2-Dioxaborolan-2-Yl)Phenyl)Silane is a high-purity, multifunctional organosilane monomer featuring four peripheral pinacol boronate ester groups. This compound is a critical building block in advanced materials science, enabling precise cross-linking and functionalization in polymer networks. It is primarily utilized by researchers and manufacturers in the organic electronics, polymer chemistry, and pharmaceutical intermediates sectors for creating sophisticated silicon-based architectures.

Application

• Cross-linking Agent for Silicone Polymers: Serves as a tetra-functional monomer for synthesizing highly cross-linked, thermally stable silicone resins and elastomers with tailored properties.
• Precursor for Organic Electronic Materials: Used in the synthesis of novel silicon-containing small molecules and polymers for applications in OLEDs, OFETs, and perovskite solar cells.
• Building Block for Metal-Organic Frameworks (MOFs) and Covalent Organic Frameworks (COFs): The boronate ester groups facilitate Suzuki-Miyaura cross-coupling reactions to construct porous, crystalline framework materials.
• Surface Modification and Functionalization: Enables the grafting of complex organic functionalities onto silicon or silica surfaces for advanced coatings and sensor applications.
• Pharmaceutical Intermediate Synthesis: Acts as a key intermediate in the development of silicon-based bioactive molecules and drug candidates.
• Dendrimer and Hyperbranched Polymer Synthesis: Provides a tetrahedral core for constructing well-defined, three-dimensional macromolecular structures.

Quality Control

Our Tetrakis(4-(4,4,5,5-Tetramethyl-1,3,2-Dioxaborolan-2-Yl)Phenyl)Silane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR (¹H, ¹³C, ¹¹B), HPLC, and elemental analysis, to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your R&D and quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C under an inert atmosphere (argon or nitrogen) due to its moisture-sensitive (hygroscopic) nature. Allow the sealed container to reach room temperature before opening to minimize moisture ingress.
