Amino acids are active biomolecules and often present in food and beverages. There is a continued interest in the development of a reliable, rapid and accurate method of analysis for assessing the quality of foods for regulatory purposes. The highly reactive amine derivatization reagent 6-aminoquinolyl-N-hydroxysuccinimidyl carbamate (AQC) can be used in a one step procedure. The compound reacts with amino acids to form stable unsymmetrical urea derivatives which are readily amenable for analysis by reversed phase HPLC.
