11-Cyanoundecyltrimethoxysilane(CAS: 253788-37-3)

11-Cyanoundecyltrimethoxysilane (CAS: 253788-37-3) is a colorless liquid with a molecular weight of approximately 342.34 g/mol. It has a high solubility in organic solvents such as toluene and dimethylformamide. The compound is reactive towards hydroxyl groups and can undergo condensation reactions. It is typically stable under normal conditions but should be handled in a fume hood to avoid inhalation and skin contact.

11-Cyanoundecyltrimethoxysilane is typically synthesized by reacting 11-aminoundecyltrimethoxysilane with carbon dioxide. The reaction is catalyzed by a transition metal catalyst and proceeds with good yield and selectivity. This process allows for the introduction of a cyanide group, which can then be used for various functionalization reactions.

11-Cyanoundecyltrimethoxysilane (CAS: 253788-37-3) is used in several industries, including pharmaceuticals, where it can be utilized as a monomer in the synthesis of drug delivery systems. In the field of polymers, it serves as a crosslinking agent to improve the mechanical properties of polymer composites. It is also used in sensor technologies for enhancing sensitivity and selectivity. Additionally, it finds application in semiconductor manufacturing for surface modification and thin film deposition.

When handling 11-Cyanoundecyltrimethoxysilane (CAS: 253788-37-3), it is essential to use appropriate personal protective equipment (PPE) such as gloves, safety goggles, and a lab coat. The compound should be handled in a well-ventilated area or a fume hood to prevent inhalation. Spills should be cleaned up with caution, using appropriate absorbent materials, and the area should be thoroughly washed down. Always refer to the Safety Data Sheet (SDS) for detailed handling and disposal information. Storage should be in a cool, dry place, away from direct sunlight and ignition sources.
