Used as a building block in organic synthesis, particularly in pharmaceuticals and agrochemicals. Its structure supports the development of bioactive molecules due to the presence of amine functionalities and a sterically hindered pyrrolidine ring. Commonly employed in the design of enzyme inhibitors and receptor ligands, especially where conformational rigidity and nitrogen-based interactions are required. Also utilized in the synthesis of spin-labeled compounds for biochemical and biophysical studies, taking advantage of its stable radical-forming potential when functionalized.
