Used in pharmaceutical synthesis as a linker or spacer in peptide-based drug development. Its structure allows for controlled spacing between functional groups, improving solubility and bioavailability of conjugated molecules. Commonly applied in the design of prodrugs and targeted delivery systems where precise molecular architecture is required. Also utilized in bioconjugation techniques for attaching payloads like fluorescent tags or cytotoxic agents to antibodies or other biomolecules. The presence of multiple carbonyl and amide groups supports stable, reversible, or cleavable bond formation under specific physiological conditions.
