| o-Phthalaldehyde Usage And Synthesis |
| Chemical Properties | Light yellow powder |
| Usage | Widely used for precolumn derivatization of amino acids in HPLC separation or Capillary electrophoresis. For flow cytometric measurements of protein thiol groups. |
| Usage | For precolumn derivatization of amino acids for HPLC separation. For flow cytometric measurements of protein thiol groups. |
| Usage | 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. |
