CAS 791028-27-8: 3-[2-(2-Aminoethoxy)ethoxy]-propanoic acid

3-(2-(2-Aminoethoxy)ethoxy)-propanoic acid is a PEG compound with two different functional groups (also known as heterobifunctional). Unlike homobifunctional PEG compounds (same functional group on both ends), this type of compounds are more versatile as have two different anchor points. 3-(2-(2-Aminoethoxy)ethoxy)-propanoic acid is used as a linker and spacer to add a PEG moiety, via pegylation (a bioconjugation technique) to proteins, peptides, oligonucleotides, small molecules and nanoparticles.

Amino-PEG2-C2-acid is a cleavable 3 unit PEG ADC linker used in the synthesis of antibody-drug conjugates (ADCs)[1].
