설명

일반 설명

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.

애플리케이션

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.
