Decyl(trimethoxy)silane(CAS: 5575-48-4)

Decyl(trimethoxy)silane (CAS: 5575-48-4) is a colorless liquid with a refractive index of 1.465 and a molecular weight of 278.38 g/mol. It has a high solubility in ethanol and acetone but is insoluble in water. Chemically, it is reactive towards hydroxyl groups, making it useful for silanization processes.

Decyl(trimethoxy)silane is synthesized by reacting decyl chloride with trimethoxysilane. Commonly, this reaction is catalyzed by a base like triethylamine, and the yield is typically high, around 90%. The product shows excellent selectivity for the desired decyl chain length.

Decyl(trimethoxy)silane is widely used in the pharmaceutical, polymer, and semiconductor industries. It is applied in drug delivery systems, as a surface modifier for polymers, and in the fabrication of semiconductors due to its ability to form stable siloxane bonds.

Handling Decyl(trimethoxy)silane requires the use of appropriate personal protective equipment (PPE), including gloves and safety glasses. It should be stored in a cool, well-ventilated area away from heat and ignition sources. In case of spill, neutralize with an appropriate absorbent and dispose of according to local regulations.
