3-Chloropropyldimethoxymethylsilane

Product code: EB-205

CAS NO.: 18171-19-2

Molecular Formula: C6H15ClO2Si

Description: 3-Chloropropyldimethoxymethylsilane is an organosilicon compound with the chemical formula C₆H₁₅ClO₂Si and CAS number 18171-19-2. It appears as a clear, colorless to pale yellow liquid at room temperature and normal pressure. It is readily soluble in organic solvents such as alcohols, ethers, and benzene. The chloropropyl and dimethoxy groups in its molecular structure confer high reactivity, enabling it to participate in coupling reactions or serve as an intermediate for synthesizing other functional silanes.
