CAS 1066-35-9

Chlorodimethylsilane

Description:

Chlorodimethylsilane, with the CAS number 1066-35-9, is an organosilicon compound characterized by its silane structure, which includes two methyl groups and a chlorine atom attached to a silicon atom. It is a colorless to pale yellow liquid with a pungent odor, and it is known for its reactivity, particularly with water, leading to the release of hydrochloric acid and the formation of silanol compounds. This substance is typically used as a reagent in organic synthesis and as a precursor in the production of silicone polymers. Chlorodimethylsilane is also utilized in surface modification processes, enhancing the properties of materials by introducing silane functionalities. It is important to handle this compound with care, as it can be corrosive and poses health hazards upon exposure. Proper safety measures, including the use of personal protective equipment and adequate ventilation, are essential when working with this chemical.

Tri-substituted Silane Reducing Agent
Organosilanes are hydrocarbon-like and possess the ability to serve as both ionic and free-radical reducing agents. These reagents and their reaction by-products are safer and more easily handled and disposed than many other reducing agents. The metallic nature of silicon and its low electronegativity relative to hydrogen lead to polarization of the Si-H bond yielding a hydridic hydrogen and a milder reducing agent compared to aluminum-, boron-, and other metal-based hydrides. A summary of some key silane reductions are presented in Table 1 of the Silicon-Based Reducing Agents brochure.
