Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and central nervous system (CNS) agents. Its structure supports the construction of complex molecules with high selectivity and potency. Commonly employed in medicinal chemistry for scaffold modification and optimization of drug candidates due to its favorable steric and electronic properties. Also utilized in the preparation of bioactive molecules requiring constrained aliphatic amines, enhancing metabolic stability and binding affinity.
