Chemical derivatization is often used to enhance the detectability of the target compounds and to improve the separation efficiency in high-performance liquid chromatography (HPLC). In this review, we describe the recent progress in the development of derivatization reagents having a

General chemical strategies which provide controlled changes in the emission or absorption properties of biologically compatible fluorophores remain elusive. One strategy employed is the conversion of a fluorophore-attached alkyne (or azide) to a triazole through a copper-catalyzed azide-alkyne coupling (CuAAC)
