| Application: | • 2,3-Diaminonaphthalene (DAN) has been used for the fluorometric measurement of nitrite/nitrate. • DAN has been used to develop a solid phase extraction-multisyringe flow injection system to spectrophotometrically detect the presence of selenium. • It has been employed in a study to develop a colorimetric assay for the detection of methylglyoxal. • It has also been used in a study to develop a novel ratiometric fluorescent probe for the in-situ detection of alkaline phosphatase activity. |
| Biochem/physiol Actions: | 2,3-Diaminonaphthalene (DAN) is used in the nitrite detection test, where it reacts with nitrite to form fluorescent 1H-naphthotriazol. DAN also reacts with selenite to form 4,5-benzopiazselenol which is detectable via absorptiometry or fluorometry. |
| General description: | 2,3-Diaminonaphthalene is also known as 2,3-Naphthalenediamine or DAN. It is one of the isomers of naphthalene bearing two amino groups, which are also called naphthalenediamines. They are usually prepared by reducing the nitronaphthalene derivative and aminating the subsequent hydroxynaphthalene derivative. |
