| Hazard Information | Back Directory | [Description]
Azide-PEG4-Tos is a heterofunctional crosslinker containing an azide (N3) group and a tosyl group. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. The tosyl group is a good leaving group for nucleophilic substitution reactions. PEG spacer increases solubility in aqueous media. | [Uses]
Azide-PEG4-Tos is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1]. Azide-PEG4-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. | [IC 50]
