Used as a protected amino alcohol building block in organic synthesis, particularly in pharmaceutical and peptide chemistry. The benzyl carbamate group acts as a protecting group for the amine, allowing selective reactions at other functional sites. The triethylene glycol-like linker provides hydrophilicity and flexibility, making it useful in the design of drug conjugates, prodrugs, and bifunctional molecules. Commonly employed in the development of PROTACs (proteolysis-targeting chimeras) and other targeted therapeutics where a spacer with solubility and biocompatibility is required. Can be deprotected under mild conditions, such as hydrogenolysis, to release the free amine for further coupling or activation.
