CAS 3550-35-4

(N,N-Dimethylamino)triethylsilane

Description:

(N,N-Dimethylamino)triethylsilane, with the CAS number 3550-35-4, is an organosilicon compound characterized by the presence of a silicon atom bonded to three ethyl groups and one dimethylamino group. This compound typically appears as a colorless to pale yellow liquid and is known for its relatively low viscosity. It exhibits properties such as moderate volatility and is soluble in organic solvents. The presence of the dimethylamino group imparts basic characteristics, making it a potential nucleophile in various chemical reactions. Additionally, (N,N-Dimethylamino)triethylsilane can act as a silane coupling agent, enhancing adhesion between organic materials and inorganic substrates. It is often utilized in the synthesis of silicone polymers and as a reagent in organic synthesis, particularly in the preparation of amine-functionalized silanes. Safety precautions should be taken when handling this compound, as it may cause irritation to the skin and eyes, and proper ventilation is recommended due to its potential volatility.

Trialkylsilyl Blocking Agent
Used as a protecting group for reactive hydrogens in alcohols, amines, thiols, and carboxylic acids. Organosilanes are hydrogen-like, can be introduced in high yield, and can be removed under selective conditions. They are stable over a wide range of reaction conditions and can be removed in the presence of other functional groups, including other protecting groups. The tolerance of silylated alcohols to chemical transformations summary is presented in Table 1 of the Silicon-Based Blocking Agents brochure.
