DACN(Tos,Suc-OH) is a click chemistry reagent containing a cycloalkyne group. The alkyne moiety within the ring has a unique bent structure and high reactivity toward cycloaddition reactions. Such strain-promoted azide-alkyne cycloadditions (SPAAC) using cycloalkynes have served for reliable molecular conjugation in a broad range of fields. The nitrogens are used as connection points for a variety of functional units. DACNs possess high thermal and chemical stability along with comparable click reactivity[1].
