M-Pyrol solvent is extremely resistant to hydrolysis from pH 2-10, even at elevated temperatures. Beyond these limits, hydrolysis to 4-(methylamino) butanoic acid occurs at a rate dependent on pH and temperature. A large body of chemistry has been developed on the reactions of strong nucleophiles with M-Pyrol solvent.
