Application

4-Nitrophenyl valerate has been used as a substrate solution to measure the rate of p-nitrophenol formation using p-nitrophenyl valerate as substrate.[1] It has also been used as a substrate to measure general esterase activity in hepatopancreas extracts.[2]

Biochem/physiol Actions

4-Nitrophenyl valerate acts as a model substrate for carboxylesterase and butyrylcholinesterase.[3]
