N-Methyl 2 Pyrrolidone M-Pyrol™ solvent
M-Pyrol solvent, a lower alkyl pyrrolidone, is an extremely powerful and versatile aprotic solvent. With its high boiling point, low vapor pressure and high stability, it is an effective solvent in numerous industry applications and can be used as a co-solvent with water, alcohols and other organic substances.
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. High-purity, low amine and low trace-metal grades are sold under the Micropure™ tradename for the electronics industry and Pharmasolve™ for the pharmaceutical industry.
