In an acid medium,amikacin(AMK) reacts with erythrosine(TIF) to form an ion-association complex,which makes the dye fade. 在酸性介质中,阿米卡星(AMK)与赤藓红(TIF)反应生成离子缔合物,导致赤藓红褪色。
Erythrosine, also known as Red No. 3, is an organoiodine compound, specifically a derivative of fluorone. It is cherry-pink synthetic, primarily used for food coloring. It is the disodium salt of 2,4,5,7-tetraiodofluorescein. Its maximum absorbance is at 530nm in an aqueous solution, and it is subject to photodegradation.
