This chemical is primarily used in organic synthesis as a building block for the preparation of more complex compounds. It serves as a key intermediate in the development of pharmaceuticals, particularly in the synthesis of active pharmaceutical ingredients (APIs) that target specific diseases. The presence of the Boc protecting group allows for selective reactions at other sites of the molecule, making it valuable in multi-step synthetic processes. Additionally, the bromo-phenyl group provides a reactive site for further functionalization through cross-coupling reactions, such as Suzuki or Heck reactions, which are widely employed in medicinal chemistry. Its application extends to the research and development of new drugs, especially in the fields of neuroscience and oncology, where modified ethylamine derivatives are often explored for their biological activity.
