Used in pharmaceutical research and development, particularly in the design of prodrugs and targeted drug delivery systems. Its structure allows for improved solubility and stability of conjugated active compounds. Commonly employed to link therapeutic agents to targeting moieties or to modify pharmacokinetic properties such as circulation time and tissue distribution. Also utilized in the synthesis of antibody-drug conjugates (ADCs) where controlled release and biocompatibility are critical. The presence of a benzyloxy group enables cleavage under specific physiological conditions, facilitating site-specific drug release.
