Dichlorobis(1,1-dimethylethyl)silane

Description:
Dichlorobis(1,1-dimethylethyl)silane, with the CAS number 18395-90-9, is an organosilicon compound characterized by its silane structure, which features a silicon atom bonded to two chlorine atoms and two tert-butyl groups (1,1-dimethylethyl groups). This compound is typically a colorless to pale yellow liquid with a distinctive odor. It is known for its reactivity, particularly in the presence of moisture, leading to hydrolysis and the formation of silanol compounds. Dichlorobis(1,1-dimethylethyl)silane is used in various applications, including as a precursor in the synthesis of silicone polymers and as a coupling agent in materials science. Its chemical properties include a relatively low boiling point and moderate solubility in organic solvents, while being less soluble in water. Safety precautions are necessary when handling this compound, as it can be irritating to the skin, eyes, and respiratory system. Proper storage in a cool, dry place away from moisture is essential to maintain its stability and prevent unwanted reactions.
