t-boc-N-amido-PEG5-azide is N-Boc protected crosslinker. The hydrophilic PEG spacer increases solubility in aqueous media. the compound can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. The Boc group can be deprotected under mild acidic conditions to form the free amine.

Boc-NH-PEG5-azide is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1]. Boc-NH-PEG5-azide is a click chemistry reagent, it contains an Azide group and can undergo copper-catalyzed azide-alkyne cycloaddition reaction (CuAAc) with molecules containing Alkyne groups. It can also undergo strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with molecules containing DBCO or BCN groups.
