Used as a key intermediate in the synthesis of bioactive molecules and pharmaceuticals, particularly in the development of proteolysis-targeting chimeras (PROTACs). Its structure allows for conjugation between E3 ligase ligands and target protein binders, facilitating targeted protein degradation. Commonly employed in medicinal chemistry research for designing novel therapeutics in oncology and neurodegenerative diseases. Also utilized in polymer chemistry as a crosslinking agent due to its ability to form stable amide and imide bonds. Shows utility in bioconjugation techniques for diagnostic and imaging agents.
