Product Description: BCN-endo-PEG2-maleimide is an ADC Linker containing 4 PEG units. BCN-endo-PEG2-maleimide contains the lyophilic bidentate macrocyclic ligand endo-BCN, which can further synthesize macrocyclic complexes. In click chemistry, endo-BCN can react with molecules containing azide groups to form stable triazoles in the absence of catalysts. Its maleimide group (-Maleimide) degrades in aqueous media and has been used in drug delivery studies.
