2,3-Diaminonaphthalene, BioReagent, suitable for fluorescence, >=98.0% (HPLC)

Analysis Note

In addition to the emission maximum at 406 nm, there are lower maxima at 426, 386 and 450 nm

Application

2,3-Diaminonaphthalene or DAN is suitable for fluorescence-spectroscopic determination of nitrite/ nitrate in milk and soy based food products. DAN is used in the fluorometric determination of selenium in biological materials.

General description

2,3-Diaminonaphthalene, also known as 2,3 DAN, is an aromatic diamino fluorescent compound designed for carrying out DAN assays. Reacting with nitrite, 2,3 DAN forms the fluorescent product, 3-naphthotriazole (NAT), determined fluorometrically.
