Fluorescent derivatization reagent, 3-aryl-7-diethylaminocoumarin derivative was synthesized and reacted with isatin. The fluorescent properties were described.
Synthesis of 4-(7-diethylaminocoumarin-3-yl)benzeneisocyanate (DACB-NCO): A highly sensitive fluorescent derivatization reagent for alcohols in high-performance liquid chromatography
4-(7-Diethylaminocoumarin-3-yl)benzeneisocyanate (DACB-NCO) was synthesized as a new fluorescent derivatization reagent for alcohols for use in high-performance liquid chromatography (hplc). Saturated alcohols (C6-C22) were derivatized in good yields into the corresponding fluorescent DACB-carbamic esters by treating with DACB-NCO. The DACB-carbamic esters of these alcohols were clearly separated on
