Dansyl Chloride

Dansyl chloride is a reactive probe for the derivatization of primary amines, including those on amino acids, peptides, and polyamines, for detection by HPLC. It has also been used for the derivatization of compounds containing phenol groups, such as steroids, for detection by MS/MS. Dansyl chloride is a fluorescent probe for proteins and enzymes. It displays excitation/emission maxima of 340/535 nm, respectively, in acetone.Formal Name: 5-(dimethylamino)-1-naphthalenesulfonyl chloride. CAS Number: 605-65-2. Synonyms: DNSCl, NSC 83616.
