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. It has also been used as a substrate to measure general esterase activity in hepatopancreas extracts.

Biochem/physiol Actions

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