2,3 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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Applications
2,3 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.

Solubility
Slightly soluble in water. Soluble in pyridine, dimethylsulfoxide, dimethyformamide, dil.hydrochloric acid, ethanol, ether and hot methanol.

Notes
Incompatible with oxidizing agents and acids.
