4-Nitrophenyl phosphate disodium salt hexahydrate CAS:4264-83-9

4-Nitrophenyl phosphate disodium salt hexahydrate is often used in biochemical research as a colorimetric substrate for alkaline phosphatase. Its application includes the detection and quantification of alkaline phosphatase activity, particularly in enzyme assays and diagnostic tests. The compound is known to hydrolyze in the presence of alkaline phosphatase, resulting in the release of a yellow product that can be easily measured using a spectrophotometer. This makes it a useful tool in various research and diagnostic applications related to phosphatase activity.
