Description

1,2,3,4,5,6-Hexakis[2-(Methyldichlorosilyl)Ethyl]Benzene is a highly functionalized, multi-branched organosilicon compound with a benzene core, serving as a critical precursor for hyperbranched and dendritic polymers. Its unique structure, featuring six reactive dichlorosilyl arms, enables the creation of complex, three-dimensional macromolecular architectures with precise control over branching density and surface functionality. This advanced intermediate is essential for researchers and manufacturers in the fields of specialty silicones, advanced materials science, and nanotechnology, where it is used to develop novel coatings, resins, and hybrid organic-inorganic systems.

Application

• Core Monomer for Dendritic/Hyperbranched Polymers: Acts as a versatile ABx-type building block for the synthesis of highly branched polysiloxanes and carbosilanes with tailored properties.
• Surface Modification Agent: Used to functionalize nanoparticles, silica, and other inorganic substrates to improve dispersion in organic matrices or introduce specific surface chemistries.
• Crosslinking Agent for Specialty Resins: Imparts high crosslink density and thermal stability to silicone-based resins and elastomers for high-performance applications.
• Precursor to Silsesquioxanes (POSS): Serves as a starting material in the controlled synthesis of polyhedral oligomeric silsesquioxanes (POSS) and related cage structures.
• Additive for Composite Materials: Enhances the interfacial adhesion and mechanical properties of polymer composites and nanocomposites.
• Research & Development: A key reagent in academic and industrial R&D for exploring new macromolecular architectures, drug delivery systems, and catalytic supports.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive) and reacts vigorously with moisture, strong acids, and organic solvents. Containers must be kept tightly sealed under an inert atmosphere (argon or nitrogen) to prevent hydrolysis and maintain stability. Keep away from heat, sparks, and open flame.
