Description

2,2,3,3,5,5,6,6-Octamethyl-1,4-Diaza-2,3,5,6-Tetrasilacyclohexane is a high-purity, cyclic organosilicon compound with a unique cage-like structure, serving as a critical precursor in advanced materials synthesis. Its value lies in its ability to introduce silicon-nitrogen frameworks into polymers and coatings, enhancing thermal stability, chemical resistance, and dielectric properties. This product is essential for R&D and production in the semiconductor, specialty polymer, and organosilicon chemical industries.

Application

• Semiconductor Precursor: Used in chemical vapor deposition (CVD) and atomic layer deposition (ALD) processes to deposit silicon carbonitride (SiCN) or silicon nitride (SiN) thin films for advanced microelectronics.
• High-Performance Polymer Synthesis: Acts as a monomer or cross-linking agent for synthesizing polycarbosilazanes and other preceramic polymers, which are pyrolyzed to form silicon carbide or silicon nitride ceramics.
• Surface Modification Agent: Imparts hydrophobic and oleophobic properties to surfaces of glass, metals, and textiles through silazane chemistry.
• Specialty Additive for Resins: Incorporated into epoxy, silicone, or other resin systems to improve thermal stability, moisture resistance, and mechanical strength.
• Catalyst and Ligand Support: Serves as a supporting ligand or precursor in organometallic chemistry and catalysis research due to its electron-donating properties.
• Research & Development: A key building block in academic and industrial R&D for developing novel organosilicon compounds, nanomaterials, and hybrid materials.

Quality Control

Our 2,2,3,3,5,5,6,6-Octamethyl-1,4-Diaza-2,3,5,6-Tetrasilacyclohexane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, NMR, and Karl Fischer titration, to ensure high purity and consistency suitable for demanding applications like semiconductor fabrication. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment.

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 nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and degradation.
