Used in pharmaceutical research as a key scaffold for developing bioactive molecules, particularly in the design of central nervous system agents, anti-inflammatory compounds, antimicrobials, and early-stage anticancer drugs. Its spirocyclic structure provides conformational rigidity, enhancing selectivity and metabolic stability in drug candidates. Also explored in agrochemicals for crop protection due to its ability to interact with biological targets in pests. Serves as an intermediate in synthesizing complex heterocycles for medicinal chemistry.
