Anwendungen
Beschreibung2,3-Diaminonaphthalene is a highly selective colorimetric and fluorometric reagent for selenium detection and also used for the fluorometric determination of nitrite. It is also useful for detection of ketones and alpha-keto acids.2,3-Diaminonaphthalene 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.Fluorometric probe for nitriteQuantify 10 nM to 10 uM of nitriteYellow orange solid soluble in DMSO
VerwendenIn a reaction similar to that of DAF-FM , 2,3- diaminonaphthalene (D-7918) reacts with the nitrosonium cation that forms spontaneously from NO to form the fluorescent product 1H-naphthotriazole.Using 2,3-diaminonaphthalene, researchers have developed a rapid, quantitative fluorometric assay that can detect from 10 nM to 10 μM nitrite and is compatible with a 96-well microplate format.
