This chemical is primarily used in organic synthesis as a building block for the preparation of more complex molecules. It is particularly valuable in peptide chemistry, where it serves as a protected intermediate for the introduction of ethylamino groups into peptide chains. The Boc (tert-butoxycarbonyl) group provides protection for the amine functionality during synthetic processes, allowing selective reactions to occur at other sites. This compound is also employed in the development of pharmaceuticals, especially in the synthesis of active pharmaceutical ingredients (APIs) that require ethylamino moieties. Additionally, it finds application in the creation of specialized polymers and materials where controlled amine functionality is essential. Its versatility makes it a useful reagent in research and industrial settings for tailored chemical modifications.
