Description

Undecyl(Trimethylsilyl) Ether CAS NO 17957-64-1 is a specialized organosilicon compound featuring a long-chain undecyl group linked to a trimethylsilyl ether moiety. This unique structure makes it a valuable intermediate and protecting group reagent in advanced organic synthesis, particularly for introducing lipophilic character or temporary masking of hydroxyl functionalities. It is essential for research and development chemists in the pharmaceutical, agrochemical, and advanced materials sectors who require high-purity, reliable building blocks for complex molecule construction.

Application

• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of active pharmaceutical ingredients (APIs), especially where lipophilicity modulation is required.
• Agrochemical Synthesis: Used in the production of specialized pesticides and herbicides as a precursor or protecting group agent.
• Advanced Material Precursor: Acts as a monomer or modifying agent in the creation of specialty silicones, surface coatings, and polymers with tailored properties.
• Organic Synthesis Reagent: Functions as a robust silylating agent for the protection of alcohols and phenols in multi-step synthetic routes.
• Liquid Crystal & Display Technology: Employed in the research and development of liquid crystal materials for electronic displays.
• Fragrance & Flavor Chemistry: Utilized as an intermediate for synthesizing specific fragrance compounds with desired volatility and stability profiles.
