Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of cardiovascular drugs and anti-inflammatory agents. It serves as a building block in the creation of pyridazinone derivatives, which exhibit biological activities such as vasodilation and platelet aggregation inhibition. Also employed in agrochemicals for the formulation of herbicides and plant growth regulators. Its structure is valuable in medicinal chemistry for designing compounds with enhanced metabolic stability and receptor selectivity.
