Used in pharmaceutical research as a key building block for synthesizing kinase inhibitors, particularly in the development of drugs targeting cancer and inflammatory diseases. Its structure supports binding to enzyme active sites, enhancing biological activity in drug candidates. Also employed in agrochemicals to improve the efficacy of crop protection agents. Commonly utilized in medicinal chemistry for structure-activity relationship (SAR) studies due to its ability to act as a bioisostere for various heterocyclic systems.
