Opis

General description

Dabsyl chloride (4-dimethylaminoazobenzene-4′-sulfonyl chloride) is a chromophoric labeling reagent used in HPLC for derivatizing amino acids. It reacts freely with all amino acids in order to form dabsyl amino acids, which are photostable and can be seen on a thin-layer chromatographic plate.

Application

For the qualitative and quantitative identification of amino acids and for the determination of N-terminal amino acids.[1][2] Used in the determination of primary and secondary amines by HPLC.[3]
