CAS 27607-77-8: Trimethylsilyl triflate

Description: Trimethylsilyl triflate, with the CAS number 27607-77-8, is a chemical compound that serves as a powerful silylating agent and a reagent in organic synthesis. It is characterized by its triflate group, which enhances its reactivity, making it useful in various chemical transformations, particularly in the protection of alcohols and amines. The compound is typically a colorless to pale yellow liquid with a pungent odor and is known for its high volatility. Trimethylsilyl triflate is soluble in organic solvents such as dichloromethane and acetonitrile but is less soluble in water. It is highly reactive and can hydrolyze in the presence of moisture, releasing triflic acid, which is a strong acid. Due to its reactivity, it must be handled with care, using appropriate safety measures to avoid skin and eye contact, as well as inhalation of vapors. Its applications extend to areas such as polymer chemistry, where it can facilitate the synthesis of complex molecules and materials.
