Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in medicinal chemistry due to its ability to form stable heterocyclic structures that enhance binding affinity to biological targets. Commonly employed in the preparation of pyridazinone-based drugs with anti-inflammatory and antitumor activities. Also utilized in agrochemical research for designing bioactive molecules with improved metabolic stability.
