Azido-PEG6-CH2CO2-t-Bu contain an azide group and a t-butyl ester. PEG spacer increases reagent's solubility in aqueous media. The azide (N3) group can react with alkyne, BCN, DBCO via Click Chemistry. The t-butyl protected carboxyl group can be deprotected under acidic condition.

Azido-PEG6-C1-Boc is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1]. Azido-PEG6-C1-Boc 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.
