Used as a key intermediate in the synthesis of biologically active compounds, particularly in pharmaceutical research. Its spirocyclic structure and protected nitrogen make it valuable for developing novel drug candidates, especially those targeting central nervous system disorders. The compound is often employed in medicinal chemistry for scaffold diversification due to its rigid three-dimensional architecture, which can improve selectivity and metabolic stability in final drug molecules. It is also utilized in the preparation of analogs for structure-activity relationship (SAR) studies.
