This chemical is primarily utilized in the field of bioconjugation and chemical biology due to its azide functional group. The azide group allows it to participate in click chemistry reactions, particularly the copper-catalyzed azide-alkyne cycloaddition (CuAAC), which is widely used for labeling, modifying, and crosslinking biomolecules such as proteins, nucleic acids, and carbohydrates. Its benzoic acid moiety provides a handle for further functionalization or attachment to other molecules, making it a versatile intermediate in the synthesis of complex molecular architectures. Additionally, the presence of a hydroxyethoxy group enhances its solubility in aqueous solutions, making it suitable for applications in biological systems. It is often employed in the development of drug delivery systems, diagnostic probes, and biomaterials.
