Product Name:Dansylamide
English Name:Dansylamide
CAS No.:1431-39-6
Aliases:Dansyl amide, 5-(Dimethylamino)naphthalene-1-sulfonamide, DNSA
Molecular Formula:C12H14N2O2S
Physical Properties:Yellow or yellowish-green crystalline powder; melting point 219-221°C. Freely soluble in organic solvents such as ethanol, chloroform and dimethyl sulfoxide, slightly soluble in water, insoluble in diethyl ether. Exhibits yellow fluorescence under UV light with good photostability.
Uses:Dansylamide is a fluorescent labeling reagent primarily used as a by-product standard of dansyl chloride for fluorescent derivatization analysis of amino acids, peptides and proteins. In biochemical and pharmaceutical analysis, it serves as a derivatization reagent in HPLC and capillary electrophoresis for qualitative and quantitative determination of amine compounds.
Technical Specifications:
