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.
Gamma-Butyrolactone is used as a chemical solvent and a cleaning agent, [15] for example in paint stripping or for cleaning graffiti. [16] Butyrolactone is a precursor to other chemicals. Reaction with methylamine gives NMP, and with ammonia gives pyrrolidone. It is also used as a solvent in lotions and some polymers. [5]

It is a colourless liquid that is miscible with water and most organic solvents. It has a characteristic odor that has been described as "ammoniacal, fishy, shellfish-like". [ 4 ] In addition to pyrrolidine itself, many substituted pyrrolidines are known.
Other alternatives to HMPA include the N,N′-tetraalkylureas DMPU (dimethylpropyleneurea) [10] [11] or DMI (1,3-dimethyl-2-imidazolidinone). [12] Tripyrrolidinophosphoric acid triamide (TPPA) has been reported to be a good substitute reagent for HMPA in reductions with samarium diiodide [ 13 ] and as a Lewis base additive to many reactions ...
It has a low solubility in water, but is soluble in a variety of organic solvents. CHP is used in the electronics industry as a photoresist stripper (usually in combination with other solvents like N-methyl-2-pyrrolidone), and as a chemical polisher of copper in circuit board fabrication. [3]
