o-Phthalaldehyde Usage And Synthesis
Chemical Properties Light yellow powder
Uses Widely used for precolumn derivatization of amino acids in HPLC separation or Capillary electrophoresis. For flow cytometric measurements of protein thiol groups.
Uses For precolumn derivatization of amino acids for HPLC separation. For flow cytometric measurements of protein thiol groups.
Uses Precolumn derivatization reagent for primary amines and amino acids. The fluorescent derivative can be detected by reverse-phase HPLC. The reaction requires OPA, primary amine and a sulfhydryl. In the presence of excess sulfhydryl, amines can be quantitated. In the presence of excess amine, sulfhydryls can be quantitated.
Definition ChEBI: A dialdehyde in which two formyl groups are attached to adjacent carbon centres on a benzene ring.
Uses Disinfectant. Reagent in fluorometric determination of primary amines and thiols.
