Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other bioactive molecules. Its structure allows for selective modification, making it valuable in medicinal chemistry for constructing complex drug candidates. Commonly employed in solid-phase peptide synthesis and PROTAC (proteolysis-targeting chimera) design due to its bifunctional nature and compatibility with coupling reactions. Also utilized in research settings to develop novel therapeutic agents targeting cancer and inflammatory diseases.
