Description

1,3-Dibromohexamethyltrisilane, Tech-95 is a high-purity organosilicon reagent featuring two reactive bromine atoms on a trisilane backbone. This compound is a critical building block in advanced materials science, valued for its ability to introduce silicon-containing functional groups and act as a versatile precursor. It is primarily utilized by R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty polymer industries for applications such as surface modification, coupling reactions, and the synthesis of novel silicon-based materials.

Application

• Silicon-Based Polymer Synthesis: Serves as a key monomer or cross-linking agent in the production of polysilanes, polysiloxanes, and other specialty silicone polymers.
• Surface Functionalization: Used to modify inorganic surfaces (e.g., silica, glass) with organic silyl groups to alter wettability, adhesion, or biocompatibility.
• Pharmaceutical Intermediates: Acts as a versatile synthon for introducing silicon into complex organic molecules during drug discovery and development.
• Agrochemical Synthesis: Employed in the creation of novel silicon-containing active ingredients or adjuvants to enhance efficacy or environmental profile.
• Coupling Agent in Composite Materials: Improves the interface between organic polymers and inorganic fillers (like glass fibers or minerals) to enhance composite material properties.
• Semiconductor & Electronics Manufacturing: Used as a precursor in chemical vapor deposition (CVD) processes for depositing silicon-containing thin films.

Quality Control

Our 1,3-Dibromohexamethyltrisilane, Tech-95 is manufactured under strict process controls to ensure batch-to-batch consistency and high chemical purity. Each lot undergoes rigorous analytical testing, including assay by GC or NMR and impurity profiling. A Certificate of Analysis (COA) detailing purity, identity, and relevant physical properties is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation. Keep away from strong acids and incompatible organic solvents.
