Used in pharmaceutical research as a key intermediate in the synthesis of antibody-drug conjugates (ADCs). Its structure enables selective attachment to cytotoxic agents, enhancing drug delivery to cancer cells while minimizing damage to healthy tissues. The carbamate linkage provides stability in circulation and controlled release inside target cells. Additionally, the polyether chain (hydroxyethoxyethoxyethyl) improves solubility and biocompatibility, making it suitable for bioconjugation applications. Also explored in prodrug design for improved pharmacokinetics.
