CAS 1719-57-9

Chloro(chloromethyl)dimethylsilane

Description:

Chloro(chloromethyl)dimethylsilane, with the CAS number 1719-57-9, is an organosilicon compound characterized by the presence of silicon, chlorine, and carbon atoms. It typically appears as a colorless to pale yellow liquid and is known for its reactivity due to the presence of multiple chloromethyl groups. This compound is used primarily in the synthesis of silicone polymers and as a coupling agent in various chemical reactions. Its structure includes two dimethyl groups attached to a silicon atom, along with a chloromethyl group, which enhances its reactivity and ability to form bonds with other materials. Chloro(chloromethyl)dimethylsilane is sensitive to moisture and can hydrolyze in the presence of water, releasing hydrochloric acid and forming silanol compounds. Safety precautions are necessary when handling this substance, as it can be corrosive and irritating to the skin and respiratory system. Proper storage in a cool, dry place, away from moisture, is essential to maintain its stability and effectiveness in chemical applications.

Specialty Silicon-Based Blocking Agent
Used as a protecting group for reactive hydrogens in alcohols, amines, thiols, and carboxylic acids. Organosilanes are hydrogen-like, can be introduced in high yield, and can be removed under selective conditions. They are stable over a wide range of reaction conditions and can be removed in the presence of other functional groups, including other protecting groups. The tolerance of silylated alcohols to chemical transformations summary is presented in Table 1 of the Silicon-Based Blocking Agents brochure.
