Dabsyl Chloride (Highly Pure) by Molecular Depot is a dabsyl chloride, the chromophoric sulfonyl chloride 4-(dimethylamino)azobenzene-4′-sulfonyl chloride. Dabsyl chloride reacts with primary and secondary amines to give intensely coloured orange sulfonamides, which are detected by absorbance rather than fluorescence. It is used to derivatise amino acids and amines for absorbance detection in chromatography, as a quencher in fluorescence resonance energy transfer pairs and in peptide chemistry. Each unit contains 100 mg. MBP supplies Molecular Depot research reagents to research labs in the United States, Canada and worldwide.
