dimethylchlorosilane

Dimethylchlorosilane is a type of organosilicon compound containing chlorosilane groups and organic side chains. It has the chemical formula (CH3)2SiHCl2 and is a clear, colorless liquid at room temperature. Dimethylchlorosilane is slightly soluble in water and has a relatively low vapor pressure.

Dimethylchlorosilane serves as a precursor in the production of a variety of silicone products, such as siloxane polymers, silane-crosslinked polymers, and silane-terminated oligomers. It is also used as a starting material in the fabrication of dielectric and insulation materials in electronic devices. This reactivity is due to the presence of the Si-Cl bond, which can be easily cleaved to form a reactive silyl cation.

Due to its susceptibility to hydrolysis, dimethylchlorosilane must be handled under controlled conditions using inert atmospheres and containing moisture-proof seals or gloves. Prolonged exposure to water can result in hydrolysis, producing silicic acid, hydrogen chloride, and di-methyl silane as byproducts. These conditions have also been shown to inhibit oxidation and to stabilize the chemical properties of the compound.

The hydrosilation reaction between dimethylchlorosilane and various hydrocarbons can result in the formation of covalent silane bonds, activating the carbon chains for labeling, stacking, or anchoring onto poly-glycol579-based surface. Handling and storage should be carried out by personnel trained in the appropriate procedures.
