N-Methyl-2-pyrrolidone (NMP) is an organic compound consisting of a 5-membered lactam. It is a colorless liquid, although impure samples can appear yellow. It is miscible with water and with most common organic solvents. It also belongs to the class of dipolar aprotic solvents such as dimethylformamide and dimethyl sulfoxide.

M-pyrol solvent is an excellent polymer solvent, paint and photoresist stripper, paint coalescent, industrial cleaner, and extraction solvent. Its N-Methyl 2 pyrrolidone structure is extremely resistant to hydrolysis from pH 2-10, even at elevated temperatures.

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.
