摘要

Abstract: 3, 6-Disulfonated 4-aminonaphthalimides are stable, highly fluorescent, water- soluble compounds. A general synthesis of these compounds is presented: a primary amine is condensed in aqueous acid with 4-amino-3, 6-disulfonaphthalic anhydride, and the product is isolated as its crystalline potassium, sodium, or lithium salt. The anhydride, whose preparation is described in detail, is interesting because it is stable indefinitely in boiling ...
