Boc-pSar8-OH is a polysarcosine-based linker with a pSar8 spacer that improves hydrophilicity and reduces immunogenicity versus PEG. Its Boc-protecting group, which can deprotected under mild acidic conditions to free the amine, enables controlled conjugation, making it ideal for ADCs, LDCs, LNPs, and advanced drug delivery systems.
