yellow to orange-yellow crystalline powder

??

Dansyl chloride is a fluorogenic reagent used for protein, N-terminal amino acid and peptide detection by reverse phase high performance liquid chromatography (HPLC). It is also used to determine the degree of labeling in chymotrypsin and ovalbumin. It acts as a precursor for the synthesis of other derivatives like dansyl amide.

?? ??

Dansyl chloride is a fluorogenic reagent which is typically employed for the derivatization of amino acids.

Safety Profile

Poison by intravenous route, When heated to decomposition it emits very toxic fumes of Cland NOx
