Highly sensitive and selective fluorescent probe for determination of Cu(II) in aqueous solution

A 5-sulfosalicylaldehyde compound, which displays high selective response for copper ions in aqueous solution, was synthesized by salicylaldehyde and concentrated sulfuric acid with high yields. The probe displayed selectivity, as evidenced by a green flu

Thiazolidine-substituted phenyl sulfonic acids

This invention relates to certain 3-(thiazolidin-2'-yl)-4-hydroxy-phenyl sulfonic acids and to a method of converting said sulfonic acids to the corresponding sulfonyl chlorides by reacting said acid with neat thionyl chloride or with thionyl chloride in
