Trichloro-[11-(2-methoxyethoxy)undecyl]silane, with the CAS number 943349-49-3, is an organosilicon compound characterized by the presence of a silane functional group and a long hydrocarbon chain. This compound features three chlorine atoms attached to the silicon atom, which enhances its reactivity and ability to form siloxane bonds. The presence of the 2-methoxyethoxy group contributes to its solubility in organic solvents and may influence its interaction with various substrates. Typically, silanes like this one are used as coupling agents, surface modifiers, or adhesion promoters in various applications, including coatings, sealants, and composites. The long alkyl chain provides hydrophobic properties, while the chlorosilane functionality allows for chemical bonding to surfaces, making it useful in enhancing the durability and performance of materials. Safety considerations include handling precautions due to the reactivity of the chlorosilane group, which can hydrolyze in the presence of moisture, releasing hydrochloric acid. Overall, this compound is significant in materials science and surface chemistry applications.
