DOTA (dodecane tetraacetic acid, also known as tetraxetan) is a complexing agent, especially for lanthanide ions. DOTA-PEG4-azide is a bifunctional linker containing chelating and azide groups for conjugation with alkyne-containing biomolecules. The structure of the reagent features a long hydrophilic PEG4 linker that separates the DOTA residue from the target molecule. The linker also enhances aqueous solubility to facilitate conjugation.

DOTA-PEG4-azide can be used to label radiotherapeutic agents or imaging probes and detect labeled tumors with PET, SPECT, and CT methods.
