6-Azidohexanoic Acid

6-Azidohexanoic acid, a six-carbon saturated fatty acid featuring an ω-terminal azide group, serves as a versatile linker for bioconjugation via copper (I) -catalyzed cycloaddition reactions (click chemistry) . This functionality enables its initial acylation to a compound, forming a derivative that can subsequently be conjugated to another compound through click chemistry, facilitating the synthesis of complex molecules.
