Used in organic synthesis as a protected hydrazide derivative for the preparation of heterocyclic compounds, particularly in the development of pharmaceuticals. The BOC (tert-butoxycarbonyl) group acts as a protecting group for amines, allowing selective reactions at other functional sites. This compound is especially valuable in the synthesis of bioactive molecules, including enzyme inhibitors and peptidomimetics, due to its ability to form stable hydrazone intermediates. It also serves as a building block in combinatorial chemistry and drug discovery research.
