FAQ

What are the physical and chemical properties of 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.

How is Decyl(trimethoxy)silane (CAS: 5575-48-4) typically synthesized?

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.

What industries use Decyl(trimethoxy)silane (CAS: 5575-48-4)?

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.

What precautions should be taken when handling Decyl(trimethoxy)silane (CAS: 5575-48-4)?

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.
