Used as a key intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals targeting central nervous system disorders. Its spirocyclic structure with fluorine substitution enhances metabolic stability and membrane permeability, making it valuable in drug design for improving pharmacokinetic properties. Commonly employed in the development of kinase inhibitors and GPCR modulators due to its ability to influence selectivity and potency. Also utilized in agrochemicals for creating novel active ingredients with improved environmental stability.
