This compound is widely used in the field of targeted protein degradation, particularly in the development of Proteolysis-Targeting Chimeras (PROTACs). It serves as a key linker component that connects the target protein-binding moiety to the E3 ubiquitin ligase-recruiting moiety, facilitating the ubiquitination and subsequent degradation of specific proteins. Its application is crucial in research focused on understanding disease mechanisms, especially in cancer and neurodegenerative disorders, where selective protein degradation can offer therapeutic benefits. Additionally, it is employed in chemical biology studies to explore protein function and validate drug targets.
