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.
