Descrizione generale

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.

Applicazioni

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.

Confezionamento

Neutral and acidic monosaccharide components in Ganoderma lucidum polysaccharide are readily labeled with 2,3-naphthalenediamine, and the resulting saccharide-naphthimidazole (NAIM) derivatives are quantified by capillary electrophoresis (CE) in borate buffer. Using sulfated-α-cyclodextrin as the chiral selector, enantiomers of monosaccharide-NAIMs are resolved
