A Novel High-Conjugated Probe of 4-(Acridone-10-yl)-Phenylethyl Chloroformate (APE-Cl) for Rapid Detection of Amino Compounds Using HPLC with Fluorescence Detection.

The fluorescence detection of amino compounds and the evaluation of their content in environmental samples are vital, not only for assessing food quality but also for studying soil organic matter. Here, we present the synthesis and application of a novel fluorescent probe, 4-(9-acridone)benzylmethyl carbonochloride (APE-Cl), for detecting amino compounds via a chloroformate reaction with fluorescence detection. The complete derivatization reaction of APE-Cl with amino compounds can be accomplished in aqueous acetonitrile within 5 min at room temperature, using 0.

Rapid Analysis of Estrogens in Meat Samples by High Performance Liquid Chromatography with Fluorescence Detection.

A novel reagent named 4-(N-methyl-1,3-dioxo-benzoisoquinolin-6-yl-oxy)benzene sulfonyl chloride (MBIOBS-Cl) for the determination of estrogens in food samples by high-performance liquid chromatography (HPLC) with fluorescence detection has been developed. Estrogens could be easily labeled by MBIOBS-Cl in NaCO-NaHCO buffer solution at pH 10.0.
