  • Alizaringelb R ist ein gelber Azofarbstoff, welcher über die Azokupplung aus Salicylsäure und diazotiertem 4-Nitroanilin hergestellt werden kann. Neben Methylrot, Methylorange und anderen Azofarbstoffen wird auch Alizaringelb R als Farbindikator bei pH-Titrationen verwendet. Ausgehend von niedrigem pH-Wert schlägt die Farbe im Bereich von 10,0 bis 12,0 von Hellgelb nach Orangerot um. Alizaringelb R zählt trotz seines Namens nicht zu den Alizarinfarbstoffen bzw. Alizarin-Derivaten, die sich vom Anthrachinon ableiten. (de)

  • アリザリンイエローR（Alizarine Yellow R）は、黄色のアゾ染料で、ジアゾカップリングで合成される。通常はナトリウム塩として生ずる。純粋なものは赤褐色の固体。酸塩基指示薬として用いられる。 (ja)
  • Amarelo de alizarina R (Laranja cromo, Laranja Mordente 1) é um corante azóico amarelo produzido por reação de copulação diazo, C.I. 14030. É usualmente encontrado como um sal de sódio. Na sua forma pura é um sólido cor de ferrugem. É um indicador de pH. É utilizado na análise de corrosão em estruturas de concreto armado. É estuda sua aplicação como reagente para a análise do cátion cobre (II). (pt)
