Amino-PEG11-alcohol is a crosslinking reagent consisting of an amino (NH2) group with a hydroxyl(OH) group. The hydrophilic PEG spacer increases solubility in aqueous media. The amino group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The hydroxyl (OH) enables further derivatization.

Amino-PEG11-OH is non-cleavable 11 unit PEG ADC linker used in the synthesis of antibody-drug conjugates (ADCs). Amino-PEG11-OH is also a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1].
