Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of herbicides and plant growth regulators. Its structure allows for functionalization at multiple sites, making it valuable in agrochemical research for creating compounds with selective biological activity. It is also employed in the preparation of pyridazine-based derivatives that show potential in medicinal chemistry, including treatments targeting inflammatory and central nervous system disorders. The ester group facilitates coupling reactions, enabling the construction of complex molecules in drug discovery pipelines.
