wikipedia: 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. It is used in the petrochemical, polymer and battery industries as a solvent, exploiting its nonvolatility and ability to dissolve diverse materials (including polyvinylidene difluoride, PVDF). It has a strong dipole moment and hydrogen bonding due to its cis-amide conformation.
