Potassium p-nitrophenyl sulfate
Based on 1 Customer Validation
Potassium p-nitrophenyl sulfate (4-Nitophenyl Sulfate potassium) serves as a chromogenic substrate for arylsulfatases. Potassium p-nitrophenyl sulfate releases nitrophenol under the cleavage action of arylsulfatases, and the activity of arylsulfatases can be quantitatively determined via colorimetric detection at 400 nm. Potassium p-nitrophenyl sulfate is commonly used in enzyme inhibition assays and metabolite analog-related studies.
