Cyclopentyltrimethoxysilane(CTMOS,Donor-CM) CAS:14348-47-2

Cyclopentyltrimethoxysilane is an organosilicon compound with the chemical formula C8H18O3Si. It is a colorless to yellowish liquid that is soluble in organic solvents such as ethanol, acetone, and chloroform.

Cyclopentyltrimethoxysilane is known for its ability to act as a coupling agent between organic and inorganic materials. This is due to its unique structure, which contains both a cyclopentyl ring and three methoxy groups attached to a silicon atom. The cyclopentyl group provides hydrophobic properties, while the methoxy groups can react with surfaces containing hydroxyl groups, forming stable covalent bonds.

As a result of these properties, Cyclopentyltrimethoxysilane is often used as an adhesion promoter and surface modifier in applications such as coatings, adhesives, and sealants. It can also be used in sol-gel processing to prepare hybrid organic-inorganic materials.
