Propyl red ( PR ) is a synthetic dye used in laboratory experiments. This versatile dye is a valuable tool for the detection of specific compounds in a variety of applications. One of its main uses is for biochemical experiments, which can be used as a dye for proteins and other macromolecules. In addition, it is crucial in identifying certain enzymes and measuring their activity in the reaction. In addition, it plays a role in the identification of specific bacteria, fungi and viruses. In addition, it also shows the practicability as a pH indicator, and the color changes according to the pH value of the solution. It is worth noting that propyl red also acts as a metal indicator, changing its color in the presence of specific metal ions.
