说明

General description

2,3-二氨基萘，也称为 2,3 DAN，是一种芳香二氨基荧光化合物，旨在进行 DAN 测定。2,3 DAN 与亚硝酸盐反应生成荧光产物 3-萘三唑（NAT），以荧光法测定。

Application

2,3-二氨基萘（DAN）适用于荧光光谱法测定牛奶和豆制品中的亚硝酸盐/硝酸盐。

DAN 用于以荧光法测定生物材料中的硒。

Packaging

无底玻璃瓶。内含物在插入的融合锥体内。

Analysis Note

除了在406 nm处的发射最大值之外，在426、386和450 nm处还具有较低的最大值

Solid phase extraction--multisyringe flow injection system for the spectrophotometric determination of selenium with 2,3-diaminonaphthalene.

A M Serra et al.

Talanta, 81(1-2), 572-577 (2010-03-02)

In the present work, a solid phase extraction (SPE) is hyphenated with an automatic MSFIA system to improve the selenite determination based on the reaction of selenite with aromatic o-diamines (such as 2,3-diaminonaphthalene (DAN)) to form the piazselenol complex. This

Determination of glyoxal and methylglyoxal in environmental and biological matrices by stir bar sorptive extraction with in-situ derivatization.

Journal of chromatography. A, 1169(1-2), 47-52 (2007-09-25)

Stir bar sorptive extraction with in-situ derivatization using 2,3-diaminonaphthalene (DAN) followed by liquid desorption and high performance liquid chromatography with diode array detection (SBSE(DAN)in-situ-LD-HPLC-DAD) was developed for the determination of glyoxal (Gly) and methylglyoxal (MGly) in environmental and biological matrices.

Plant catechols and their S-glutathionyl conjugates as antinitrosating agents: expedient synthesis and remarkable potency of 5-S-glutathionylpiceatannol.

Maria De Lucia et al.

Chemical research in toxicology, 21(12), 2407-2413 (2009-06-24)

With a view to elucidating the structural requisites for effective antinitrosating properties in plant polyphenolics and their metabolites, we have undertaken a comparative investigation of the nitrite scavenging effects of representative catechol derivatives of dietary relevance in the 2,3-diaminonaphthalene (DAN)
