Compounds containing .alpha.-discarbonyl groups are rendered capable of fluorescent emission by conjugation with carboxylic acid-terminated ortho-diaminoaryl reagents. The carboxylic acid groups serve as ionizable moieties which facilitate the conjugation reaction, and are retained in the conjugation product to enable, or enhance the ability of, the conjugated compounds to be separated in chromatographic and electromigration separation processes, notably electrophoresis. Ortho-dinitro derivatives of the reagents are also disclosed, these derivatives offering the advantage of stability as well as the ability to be used directly in the reaction in the presence of a reducing agent.
含有α-二羰基基团的化合物通过与羧酸末端的邻二氨基芳基试剂共轭,从而具有荧光发射能力。羧酸基团作为可离子化的基团,促进了共轭反应,并在共轭产物中保留,以使共轭化合物能够在色谱和电泳分离过程中被分离或增强其能力。还公开了试剂的邻二硝基衍生物,这些衍生物具有稳定性的优势,并且可以在还原剂存在的情况下直接用于反应。
