Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of histamine H3 receptor antagonists. It plays a role in creating compounds aimed at treating neurological disorders such as narcolepsy, ADHD, and cognitive impairments. Its spirocyclic structure provides conformational rigidity, enhancing selectivity and binding affinity in drug molecules. Also explored in medicinal chemistry for optimizing pharmacokinetic properties due to its metabolic stability and favorable solubility profile.
