The invention relates to novel fluorescent dyes with multiple negatively charged groups in their ionized form which are 9-aminoacridines or 1-aminopyreneshaving of one of the following general formulae A-E: or salts or protonated forms thereof, wherein the ionizable groups are typically selected from the following: OH, SH, COOH, SO3H, OSO3H,SO2NHCN, P(O)(OH)2, P(O)(OH)2. The invention further relates to the use of these dyes as fluorescent tags, in particular for reducing sugars and glycans, and to carbohydrate-dye conjugates comprising these dyes as well as to methods for preparing the same.
