Used primarily in pharmaceutical research as a key intermediate in the synthesis of biologically active compounds. It serves as a building block in the development of kinase inhibitors, which are important in cancer therapy and inflammatory disease treatment. Its structure allows for selective modification, making it valuable in creating targeted drug candidates. Also utilized in the study of neurological pathways due to its ability to interact with certain enzyme systems in the brain. Commonly found in early-stage drug discovery for optimizing potency and selectivity of new medicinal compounds.
