Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other biologically active compounds. Its structure allows for selective substitution, making it valuable in drug discovery for building molecules with high target specificity. Commonly employed in the preparation of antitumor, antiviral, and anti-inflammatory agents. Also utilized in agrochemicals for the design of novel pesticides and herbicides due to its ability to enhance metabolic stability and binding affinity in active ingredients.
