643-79-8 Usage

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.

Uses

Disinfectant. Reagent in fluorometric determination of primary amines and thiols.

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.

Definition

ChEBI: A dialdehyde in which two formyl groups are attached to adjacent carbon centres on a benzene ring.
