Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and biologically active compounds. It serves as a protected form of piperidine, allowing selective reactions at other sites in the molecule. Commonly employed in the synthesis of alkaloids, antipsychotics, and other nitrogen-containing heterocycles. Its tosyl group can be removed under mild conditions, making it valuable in multi-step synthetic routes. Also utilized in the development of agrochemicals and functional materials due to its stability and reactivity profile.
