Product Data Sheet
4-(4-Nitrophenylazo)resorcinol
Catalog No. A45248
4-(4-Nitrophenylazo)resorcinol acts as a fluorescent dye with pH indicator properties. It exhibits a color change from yellow at pH levels below 11 to purple above pH 13, and can shift to dark blue in the presence of magnesium salts in slightly alkaline conditions. This compound is also useful for detecting ammonium ions, with the resulting color of ammonium chloride or ammonium hydroxide solutions varying based on the concentration of the dye used. Its properties make it valuable for applications in analytical chemistry and environmental monitoring.
