Alkyne-PEG3-COOH is a bifunctional triethyleneglycol 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 that are useful in the synthesis of water soluble conjugates.
