Application

Phthaldialdehyde Reagent has been used for the derivatization plasma samples prior to high performance liquid chromatography.
Useful for investigators requiring an alternate sulfhydryl moiety. Requires addition of desired sulfhydryl compound for measuring amines. Requires addition of amine to measure sulfhydryls.
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.

Linkage

Same as P 0532, but contains no 2-mercaptoethanol.
