Background:

Dansyl chloride is a reagent that reacts with primary amino groups in both aliphatic and aromatic amines to produce stable blue- or blue-green-fluorescent sulfonamide adducts. Dansyl chloride is widely used to modify amino acids; specifically, protein sequencing and amino acid analysis. It can also be used to label hydroxyl and carboxylic acid functional groups.
