Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of nitrogen-containing heterocyclic drugs. It serves as a building block in agrochemicals for creating herbicides and plant growth regulators. Also employed in research laboratories for designing novel bioactive molecules due to its pyridazine core, which is known to exhibit antimicrobial and anti-inflammatory activities. Its chloro and phenyl substituents allow for further functionalization through cross-coupling reactions, making it valuable in medicinal chemistry and drug discovery.
