2,3-DIAMINONAPHTHALENE(Cas 771-97-1) Usage

Reactions

2,3-diaminonaphthalene (DAN) is a fluorometric probe for nitrite. It reacts with nitrosonium, which is formed from nitrite at low pH, to form the fluorescent dye 1 H-naphthotriazole. This method can be used to detect 10 nM to 10 uM of nitrite (NO2-) and is compatible with 96-well format.Reaction of 2,3-Diaminonaphthalene with NO2.

Purification Methods

Crystallise the diamine from water, or dissolve it in 0.1M HCl, by heating to 50o. After cooling, the solution is extracted with decalin to remove fluorescent impurities and centrifuged. [Beilstein 13 IV 346.]
