一般描述
柠檬黄(Cl 19140)也称为酸性黄23，是一种多聚阴离子水溶性染料。作为一种磺酸染料，可通过对氨基苯磺酸与3-羧基-1-(4-磺酸苯基)-5-吡唑啉酮的反应合成。
应用
在使用离子对液相色谱-光电二极管阵列-电喷雾质谱检测器法对食品样品中柠檬黄进行测定时，可采用本品柠檬黄作为参考标准品。
柠檬黄也可用于荧光桃红-柠檬黄法染色细胞包涵体，如病毒聚集体和嗜酸性粒细胞颗粒。可替代Mallory三色染液中的橙黄G，也可配制甲基紫-柠檬黄混合液，染色粪涂片和黏膜刮片中的隐孢子虫。

Spatial patterns of gene expression in living organisms orchestrate cell decisions in development, homeostasis, and disease. However, most methods for reconstructing gene patterning in 3D cell culture and artificial tissues are restricted by patterning depth and scale. We introduce a

Analytical UV absorption detection for microfluidic devices, capillary electrophoresis, and even high-performance liquid chromatography is hampered by the small detection volumes, short absorption paths, and the need to sample at a high rate with a stable background and low noise.
