Dansyl chloride is a fluorescent labeling reagent that reacts with primary and secondary amines to form stable blue or blue-green fluorescent sulfonamide adducts. It readily labels aliphatic and aromatic amines through reaction with amino groups, making it a valuable tool for biochemical analysis. Dansyl chloride is widely used for amino acid derivatization, protein sequencing, and amino acid composition analysis, enabling sensitive fluorescence-based detection and quantification of amine-containing biomolecules.
