Description

1,2-Dichlorodisilane is a highly reactive organosilicon compound that serves as a critical precursor in advanced materials synthesis. Its value lies in its ability to introduce silicon-chlorine bonds into complex molecular structures, enabling precise control over material properties. This chemical is essential for researchers and manufacturers in the semiconductor and specialty chemical industries, particularly for developing silicon-based thin films and novel polymers.

Application

• Chemical Vapor Deposition (CVD) and Atomic Layer Deposition (ALD): A key silicon source for depositing high-purity silicon, silicon carbide, or silicon nitride thin films on semiconductor wafers.
• Precursor for Organosilicon Synthesis: Used as a building block for synthesizing more complex disilanes, cyclic silanes, and silicon-based polymers.
• Surface Functionalization: Employed to modify material surfaces with specific silicon-containing groups to alter wettability, adhesion, or reactivity.
• Research & Development: A valuable reagent in academic and industrial labs for exploring new silicon chemistry and developing advanced materials.
• Production of Silicon-Containing Intermediates: Serves as an intermediate in the manufacture of specialized silicones and other silicon-based compounds.

Quality Control

Our 1,2-Dichlorodisilane is produced and handled under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including gas chromatography (GC) and spectroscopic analysis, to ensure high purity and consistency. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee it meets your specific research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and hygroscopic (moisture-sensitive) nature, this product must be stored under an inert atmosphere (argon or nitrogen) in a cool, dry, and well-ventilated area. Recommended storage temperature is between 2°C and 8°C to maintain stability. Keep away from heat, sparks, open flames, and incompatible materials such as strong oxidizers, bases, and moisture.
