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.
