Product Name:Dimethylsilane
English Name:Dimethylsilane
CAS No.:1111-74-6
Aliases:Dihydrodimethylsilane, Dimethylhydridosilane
Molecular Formula:C2H8Si
Physical Properties:At normal temperature and pressure, it is a colorless flammable gas with a slight pungent odor. Melting point approximately -150 °C, boiling point approximately -20 °C, relative density (water = 1) approximately 0.68 at -20 °C. Sensitive to moisture; upon contact with water, it hydrolyzes releasing hydrogen gas. Easily soluble in non-polar organic solvents such as toluene and hexane.
Uses:Dimethylsilane is an important organosilicon source and silylating reagent, widely used in chemical vapor deposition (CVD) for the preparation of silicon carbide and silicon dioxide thin films. In organic synthesis, it is used as a hydrosilylation reagent to introduce dimethylsilyl functional groups. It can also be used to prepare polycarbosilane and other high-performance ceramic precursors.
Technical Specifications:
Purity: ≥98% (by GC)
Melting point: approx. -150 °C
Boiling point: approx. -20 °C
Molecular weight: 60.17
Storage: sealed, low temperature, protected from light, away from water sources and oxidizing agents
