Used as a key intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals and agrochemicals. Its spirocyclic structure with a trifluoromethyl group enhances metabolic stability and lipophilicity, making it valuable in drug design for improving pharmacokinetic properties. Commonly employed in the development of fluorinated analogs to increase potency and resistance to oxidative degradation. Also utilized in the preparation of specialty chemicals where fluorine substitution is needed to fine-tune reactivity or physical properties.
