4-Nitrophenol sodium salt is a compound that serves as an important tool in various areas of chemical research. It is widely used as a colorimetric probe due to its ability to release a yellow color upon protonation, which is quantifiable and useful in enzyme activity assays, particularly those involving phosphatases and glycosidases. The compound is also employed in studies of electron transfer processes because the nitro group is a good electron acceptor, making 4-Nitrophenol sodium salt a model compound for understanding redox reactions. In environmental chemistry, it is used to monitor the presence and activity of pollutants and to assess the efficiency of wastewater treatment processes that involve the removal of nitrophenolic compounds. Additionally, the sodium salt form enhances solubility in water, making 4-Nitrophenol sodium salt convenient for use in a variety of aqueous solutions in research applications.
