DBCO-C2-alcohol is widely utilized in bioorthogonal chemistry due to its DBCO (dibenzocyclooctyne) group, which enables rapid and selective reactions with azides without the need for catalysts. This property makes it highly valuable in labeling and imaging applications, where it is used to tag biomolecules such as proteins, peptides, and nucleic acids for visualization in live cells or tissues. It is also employed in the development of antibody-drug conjugates (ADCs), where it facilitates the precise attachment of therapeutic agents to antibodies. Additionally, DBCO-C2-alcohol is used in surface modification and material science to functionalize polymers, nanoparticles, and other substrates for targeted applications. Its versatility and efficiency in click chemistry reactions make it a key tool in drug discovery, diagnostics, and bioconjugation strategies.
