Used as a key intermediate in organic synthesis, particularly in the preparation of functionalized piperidines and other nitrogen-containing heterocycles. Its primary application lies in pharmaceutical research and development, where it serves as a protected or activated pyridine derivative for coupling reactions. The triflate group enables palladium-catalyzed cross-coupling reactions, allowing the introduction of various substituents. The 2-(trimethylsilyl)ethyl group acts as a protecting group that can be removed under mild conditions, making it suitable for multi-step syntheses. It is especially valuable in the construction of complex molecules such as bioactive compounds and drug candidates.
