4,5-Dihydro-2-methoxy-1H-imidazole (MDHI) is a multifunctional label for use in proteomic studies. MDHI is lysine specific and by increasing the ionization of lysine terminated tryptic fragments it also increases the overall sequence coverage

4,5-Methylenedioxy-1,2-phenylenediamine dihydrochloride is a fluorescence tag for ?-keto acids. It is also required for the derivatization of sialic acids in presence of dilute sulfuric acid. The method allows determination of sialic acids.
