Provided are modified cycloalkyne compounds; and methods of use of such compounds in modifying biomolecules. Embodiments include a cycloaddition reaction that can be carried out under physiological conditions. The cycloaddition reaction involves reacting a modified cycloalkyne with an azide moiety on a target biomolecule, generating a covalently modified biomolecule. The selectivity of the reaction and its compatibility with aqueous environments provide for its application in vivo and in vitro.
