Products Description
3-Chloropropyltrichlorosilane is an organosilicon compound with the chemical formula Cl(CH₂)₃SiCl₃ and CAS number 2550-06-3. It appears as a clear liquid ranging from colorless to pale yellow. It is primarily used in the synthesis of silane coupling agents such as KH-550 and Si69, as well as organic silicon intermediates and high-molecular-weight polymers. It is typically prepared by the reaction of trichlorosilane with allyl chloride in the presence of a platinum catalyst.

Applications:
3-Chloropropyltrichlorosilane (Cl(CH₂)₃SiCl₃) is one of the most important intermediates in the production of silane coupling agents. It serves as a key raw material for manufacturing various silane coupling agents, including chloropropyltriethoxy (or trimethoxy) silanes, aminopropyltriethoxy (or trimethoxy) silanes, and bis(triethoxysilylpropyl) tetrasulfide. These products are essential additives in rubber formulations and glass fiber-reinforced composite materials.
