5（6）-氧若丹明6G乙二胺

5（6）-氧若丹明6G乙二胺是开发若丹明生物共轭物的基础。通常，若丹明6G共轭物比四甲基若丹明共轭物具有更高的荧光量子产率，并且具有良好的光稳定性。罗丹明6G的激发和发射波长（λ| ex 524 nmλ| em 551 nm）介于荧光素和四甲基若丹明衍生物之间，使5（6）-CR6G成为多色荧光成像应用的另一种颜色选择。5（6）-CR6G是两种羧基若丹明6G异构体的混合物。

5(6)-Caroxyrhodamine 6G ethylenediamine is a building block for developing rhodamine bioconjugates. In general, rhodamine 6G conjugates have higher fluorescence quantum yields than tetramethylrhodamine conjugates, as well as good photostability. The excitation and emission wavelengths(λ|ex|524 nm λ|em|551 nm) of rhodamine 6G fall between those of fluorescein and tetramethylrhodamine derivatives, making 5(6)-CR6G another color choice for the multicolor fluorescence imaging applications. 5(6)-CR6G is the mixture of two carboxy rhodamine 6G isomers.
