一般描述

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。

应用

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。

包装

无底玻璃瓶。内含物在插入的融合锥体内。

分析说明

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

The reaction of 2,3-diaminonaphthalene (DAN) with Se(IV) to form a fluorescent Se-DAN complex is the basis of a fluorometric method for determination of Se. With the aid of metabolically incorporated 75Se the method was critically re-examined. The study showed that

In this Communication, we report on the first preparation of conjugation polymer poly(2,3-diaminonaphthalene) (PDAN) microspheres via chemical oxidation polymerization of 2,3-diaminonaphthalene (DAN) monomers by ammonium persulfate (APS) at room temperature. We further demonstrate the use of PDAN microspheres as a
