Methyldichlorosilane

Description:

Methyldichlorosilane, with the CAS number 75-54-7, is an organosilicon compound characterized by its chemical formula CH3Cl2Si. It is a colorless to pale yellow liquid with a pungent odor, commonly used as an intermediate in the production of silicone polymers and other silanes. This compound is notable for its reactivity, particularly in hydrolysis, where it can react with water to produce silanol and hydrochloric acid. Methyldichlorosilane is also used in the synthesis of various siloxanes and as a coupling agent in the formulation of silicone materials. It has a relatively low boiling point and is volatile, which necessitates careful handling due to its potential health hazards, including irritation to the skin, eyes, and respiratory system. Additionally, it is classified as a hazardous substance, requiring appropriate safety measures during storage and use. Overall, methyldichlorosilane plays a significant role in the chemical industry, particularly in the development of silicone-based products.

METHYLDICHLOROSILANE

CAS: 75-54-7

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.

Dichloromethylsilane

CAS: 75-54-7

Dichloromethylsilane (DCS) is a chemical compound that is used in the synthesis of silicone rubber, silicone elastomers, and silicone sealants. It can also be used as a cross-linking agent for polymers such as polyurethane, epoxy resin, and silicone. The synthesis of DCS is achieved by reacting chlorosilanes with methyl alcohol or methyl chloride in the presence of an acid catalyst. DCS exhibits high chemical stability and can be activated at room temperature. This product has been shown to be useful for fabricating medical devices that are implanted into the human body because it does not react with water or blood.
