Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. Its structure allows for selective substitution reactions, making it valuable in creating active pharmaceutical ingredients (APIs) targeting tyrosine kinases. Commonly employed in research and development of antitumor agents due to its ability to modify biological activity when incorporated into larger molecules. Also utilized in agrochemicals for designing herbicides and pesticides, leveraging its reactivity and stability in organic transformations.
