Pyrene-PEG3-azide is a pyrene labeled PEG linker containing an azide group, which enables Click Chemistry labeling with any alkyne-bearing molecules and thus turns any molecule into pyrene-bearing probe.
Pyrene-amido-PEG4-azide is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1]. Pyrene-amido-PEG4-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.
