Derivatizing reagent, fluorescent pyridones

We inferred that these properties might be exploited in a series of unique derivatizing reagents designed specifically for trace analysis of organic compounds using HPLC separation and fluorescence detection. The use of these pyridones for the analytical purposes reported here is based on their acidic properties. Treatment of a lH-2-pyridone with a base converts the pyridone to its salt. 

Pyridone Acid Chlorides as Fluorescent Derivatizing Reagents. A second derivatizing reagent, a fluorescent acid chloride, was synthesized from the sodium salt of 3-phenyl-2(lH)pyridone (IV).
