Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of cardiovascular and anti-inflammatory drugs. Its structure allows for functional modifications that enhance drug efficacy and selectivity. Commonly employed in medicinal chemistry for constructing pyridazine-based heterocyclic compounds, which show biological activity in enzyme inhibition and receptor modulation. Also utilized in agrochemical research for designing herbicides and plant growth regulators due to its ability to interact with biological targets in pests and pathogens.
