Used as a protected diamine building block in peptide synthesis and medicinal chemistry. The compound contains two Boc (tert-butoxycarbonyl) protecting groups—one on a piperidine nitrogen and another on an amino group—making it ideal for selective deprotection and stepwise construction of complex molecules. Commonly employed in the synthesis of pharmaceuticals, especially protease inhibitors and kinase inhibitors, where controlled amine reactivity is required. Its stability under various reaction conditions allows for use in multi-step organic transformations, including coupling reactions and heterocycle formation. Also utilized in the development of APIs (active pharmaceutical ingredients) requiring masked amine functionalities.
