别名 媒染黄;茜素黄R;间硝基苯偶氮水杨酸钠;Metachrome Yellow; Salicyl Yellow; 5-(3-Nitrophenylazo)salicylic acid sodium salt; Alizarin Yellow 2G; Metachrome Yellow Mordant Yellow 1
生化机理 Alizarin Yellow GG is a useful acid base indicator with a dye content of 50% and a color index number of 14025, commonly used in nutrient media preparation. Studies indicate that removal of the dye is pH dependent and can be withdrawn from aqueous solutions by irradiating the sample with radiation at 355nm and nano ZnO particles. Alternate studies show that Alizarin Yellow GG is directly mutagenic to the Salmonella/microsome system. Furthermore, Alizarin Yellow GG can inhibit conjugation transfer of depressive R-factors RI drd and R 64 drd.
应用 用作酸碱指示剂,pH值10.0(亮黄)~12.0(棕黄)。还用作生物染色剂。常用0.1g溶于100ml50%乙醇中。
