Used as a key intermediate in organic synthesis, particularly in the preparation of nitrogen-containing heterocyclic compounds. Its protected dihydropyridazine structure makes it valuable in pharmaceutical research for constructing complex molecules, including bioactive agents and functional materials. The tert-butyl groups provide steric protection, allowing selective reactions at other sites in the molecule, which is advantageous in multi-step synthesis. It is also employed in the development of novel catalysts and ligands due to its stable yet reactive framework.
