Fmoc-N-amido-PEG4-propionic acid is a PEG-based spacer and synthetic linker building block used to introduce a defined hydrophilic and flexible segment into multistep conjugation designs. The PEG chain can increase molecular spacing and provide a modular connection between reactive groups without serving as a dedicated cleavage trigger. This derivative contains peg4 spacer together with terminal functionality selected for further synthesis. The available reactive group is no dedicated antibody-reactive group unless activated/functionalized; terminal functionality depends on the specific peg derivative. The opposite terminus provides terminal carboxylic acid; activate for coupling to an amine-bearing payload. Coupling and deprotection conditions should be matched to the terminal groups and the intended order of assembly.
