Cas no 1101-84-4 (L-Lysine,N6-[[5-(dimethylamino)-1-naphthalenyl]sulfonyl]-)

L-Lysine,N6-[[5-(dimethylamino)-1-naphthalenyl]sulfonyl]- is a modified amino acid derivative featuring a dansyl (5-dimethylaminonaphthalene-1-sulfonyl) group attached to the ε-amino position of L-lysine. This compound is primarily utilized as a fluorescent probe or labeling reagent in biochemical and biophysical research due to its strong fluorescence properties and sensitivity to environmental changes. The dansyl group enhances its utility in studying protein interactions, conformational changes, and localization. Its high solubility in aqueous and organic solvents, along with stable fluorescence emission, makes it suitable for spectroscopic and chromatographic applications. The compound is also valuable for derivatizing peptides or proteins to facilitate detection and analysis.
