Used as a versatile linker in bioconjugation, enabling the attachment of biomolecules such as proteins, peptides, or antibodies to other functional groups or surfaces. Its azide group allows for click chemistry reactions, particularly with alkyne-containing compounds, facilitating efficient and selective coupling. Commonly applied in drug delivery systems, where it helps in creating targeted therapeutic agents by linking drugs to carriers. Also utilized in the development of biosensors and diagnostic tools, where it aids in immobilizing biomolecules onto sensor platforms for enhanced detection capabilities. Additionally, it plays a role in material science for surface modification, improving the biocompatibility of materials used in medical devices or implants.
