“A New Fluorogenic Reagent for Labelling Carboxylic Acids in HPLC,” by E. Gikas, M. Derventi, I. Panderi, A. Vavayannis, M. Kazanis, and M. Parissi‐Poulou, J. Liq. Chrom. & Rel. Technol.® 2002, 25 (3), 381–395; and “Determination of Valproic Acid in Human Plasma by HPLC with Fluorescence Detection,” by S. Rompotis, M. Parissi‐Poulou, E. Gikas, M. Kazanis, A. Vavayannis, and I. Panderi, J. Liq. Chrom. & Rel. Technol.® 2002, 25 (18), 2833–2847.
It should be noted that the correct name of the reagent that was synthesized and applied to the analysis in both papers is N‐(7‐methoxy‐4‐methyl‐2‐oxo‐2H‐6‐chromenyl)‐bromoacetamide instead of N‐(4‐bromomethyl‐7‐hydroxy‐2‐oxo‐2H‐6‐chromenyl)bromoacetamide, which was stated in error throughout the first paper and on page 2834 and in the Scheme 1 legend (page 2837) in the second paper.
