endo-BCN-PEG3-amine is a click chemistry linker containing a BCN and an amine group. The BCN group can react with azide-tagged biomolecules under mile condition. The amino group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc.

endo-BCN-PEG3-NH2 is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1]. endo-BCN-PEG3-NH2 is a click chemistry reagent, it contains a BCN group that can undergo strain-promoted alkyne-azide cycloaddition (SPAAC) with molecules containing Azide groups.
