Azide-PEG3-Tos Chemical Properties,Usage,Production

Description

Azide-PEG3-Tos is a heterobifunctional PEG linker.The azide (N3) group is reactive with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. Tosyl group is a good leaving group for nucleophilic substitution reactions.

Uses

Azide-PEG3-Tos is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1]. Azide-PEG3-Tos is also a non-cleavable 3 unit PEG ADC linker used in the synthesis of antibody-drug conjugates (ADCs)[2]. Azide-PEG3-Tos 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.
