Description

Tetrachlorodimethyldisilane is a versatile organosilicon compound primarily used as a key intermediate in the synthesis of more complex silane derivatives. Its value lies in its reactive chlorosilane groups, which allow for controlled functionalization and cross-linking in advanced material science. This product is essential for researchers and manufacturers in the semiconductor, specialty polymer, and pharmaceutical intermediate industries seeking to develop novel silicon-based materials.

Application

• Semiconductor Manufacturing: Acts as a crucial precursor for chemical vapor deposition (CVD) and atomic layer deposition (ALD) processes to create silicon carbide (SiC) or silicon nitride (SiN) thin films.
• Silicone Polymer Synthesis: Serves as a cross-linking agent or chain extender in the production of high-performance, heat-resistant silicone resins and elastomers.
• Surface Modification: Used to functionalize inorganic surfaces (e.g., silica, glass) with organic groups, altering hydrophobicity, adhesion, and compatibility.
• Pharmaceutical Intermediates: Employed in the synthesis of organosilicon compounds with potential biological activity or as protecting groups in complex organic synthesis.
• Adhesive & Sealant Formulations: Imparts improved thermal stability and moisture resistance when incorporated into specialty adhesive systems.
• Research & Development: A valuable building block in academic and industrial R&D for exploring new silicon chemistry and material properties.

Quality Control

Our Tetrachlorodimethyldisilane is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including Gas Chromatography (GC) and NMR spectroscopy, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles 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 area at room temperature (15-25°C). Due to its hygroscopic and highly volatile nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and decomposition. Keep away from strong acids and organic solvents.
