N-Methylpyrrolidone Introduction:

N-Methylpyrrolidone also known as NMP or 1-methyl-2-pyrrolidone. 1-methyl-2-pyrrolidone is a solvent used in a range of products. The average consumer is most likely to encounter it in paint strippers, even though safer alternatives exist. NMP has been closely linked to developmental impacts including miscarriages.

What Products Contain NMP?

Paint Strippers: NMP is a key ingredient in a variety of paint and coating removers sold in the U.S.
Paints and other coatings: This chemical is also used in a range of coating products sold by popular retailers.
Other Products: Some adhesives, cleaners, dyes, inks, and pesticides also contain NMP.

NMP Application:

N-Methylpyrrolidine can be used as a starting material to synthesize:
N-methyl pyrrolidine-zinc borohydride is a reducing agent for reduction of aldehydes, ketones, acid chlorides and esters. NMP is also used in the reductive amination of aldehydes and ketones to their corresponding amines.
N-alkyl-N-methyl-pyrrolidinium bis(trifluoromethanesulfonyl)imide ionic liquids.
N-methylpyrrolidine-2-one hydrotribromide applicable as a catalyst for aziridination of alkenes.

How am I Exposed to This Chemical?

If you are a consumer or worker who uses products with NMP, you may be exposed through skin contact or by inhaling the vapors.
You are most likely to be exposed to NMP while using paint and coating removers containing the chemical.
Contact with skin may be direct if the product touches your hands, or indirect, if NMP vapor is absorbed through any uncovered skin (e.g. neck or head).
