Used in pharmaceutical research as a key intermediate in the synthesis of biologically active compounds, particularly in the development of central nervous system agents. Its spirocyclic structure provides structural rigidity, making it valuable in medicinal chemistry for enhancing selectivity and metabolic stability in drug candidates. Commonly employed in the design of kinase inhibitors and receptor modulators due to its favorable binding properties and solubility profile. Also utilized in the preparation of novel heterocyclic systems for screening in anti-inflammatory and neurodegenerative disease studies.
