Used primarily as an intermediate in the synthesis of pharmaceutical compounds, this compound plays a key role in the development of selective kinase inhibitors. It is particularly valuable in the construction of spirocyclic frameworks that enhance metabolic stability and binding affinity in drug candidates. Its structure supports conformational rigidity, which is beneficial for improving potency and selectivity in central nervous system (CNS)-targeted therapeutics. Additionally, it has been employed in the preparation of bioactive molecules with potential antiviral and anti-inflammatory properties. The tosylate salt form improves crystallinity and handling during synthetic processes, making it suitable for scale-up in medicinal chemistry.
