Alkyne-PEG2-carboxylic acid is a bifunctional diethyleneglycol derivative bearing a carboxy group and an alkyne moiety. The former can be activated with peptide coupling reagents like PyBOP or carbodiimides like EDC to form a stable amide linkage with amines. The alkyne group can be coupled with azides in a CuAAC reaction.
PEGs are hydrophilic linkers useful in synthesizing water-soluble conjugates.
