4-Nitrophenyl phosphate disodium salt hexahydrate（Cat No.:L013926）is a water-soluble, yellow crystalline compound with the molecular formula C6H4NO6PNa2·6H2O. It is widely used as a chromogenic substrate in enzyme assays, particularly for alkaline phosphatase. Upon enzymatic hydrolysis, it releases 4-nitrophenol, which turns yellow under alkaline conditions, allowing easy quantification via spectrophotometry. Its stability and solubility in aqueous solutions make it ideal for biochemical and diagnostic applications. This compound is typically stored at low temperatures in dry conditions to preserve its integrity and should be handled using appropriate lab safety procedures to avoid degradation or contamination.
