Polyethylene glycol derivatives with few units (in this case, 3 monomeric units) are excellent linkers for conjugation of biomolecules to run reactions in aqueous conditions and increase the hydrophilicity of the compounds resulting from conjugation.

Terminal alkynes readily react in сlick сhemistry reactions with various azides in the presence of copper (I) salts, and maleimide derivatives react with thiols. This is especially relevant for proteins and peptides that contain free -SH groups.

Alkyne-PEG3-maleimide is a cross-linker that can be widely used in chemistry, biology, and related areas.
