Description and Uses
5-Aminonaphthalene-1-sulfonic acid is an deriva- tizing agents in the precolumn derivatization of some chiral phenoxy acid. Cu(II) based on a dansyl derivative was synthesized with 29.2% overall yield by a seven-step synthetic procedure from the readily available starting material 5-aminonaphthalene-1-sulfonic acid.
