NMP, 1-Methyl-2-Pyrrolidone, Lab Grade (CAS 872-50-4) is a polar aprotic, low viscosity liquid with a high boiling point and strong solvency for organic and inorganic compounds. Assay is a minimum of 99.0%, with water at a maximum of 0.05 wt% and chloride at a maximum of 1 ppm. It looks colorless to slightly yellow, free of particulate matter, with a mild amine odor. The boiling point is 202 °C at 760 mmHg, the melting point is minus 24 °C, the flash point is 91 °C, and it’s fully miscible in water. The formula is C5H9NO and the molecular weight is 99.13. On this page you’ll find the Safety Data Sheet, Technical Data Sheet, allergen, BPA, PFAS/PFOS free and non irradiation statements, plus Certificates of Analysis.
NMP does a lot of jobs. Teams use it as a solvent, a reagent and a cleaning agent, in petrochemical work, and in making pigments, insecticides, herbicides and fungicides. It’s also used in place of chlorinated hydrocarbons. The trouble starts when a solvent shows up with no paperwork or the wrong size, and your project stalls. That’s where Lab Alley steps in as your guide. The SDS, Technical Data Sheet and Certificates of Analysis are right on this page, and sizes run from a 500ml bottle up to a 55 gallon drum, with case packs in between. If your order needs hazmat handling, we take care of it from start to finish. Choose your size, set up Autoship if you reorder, or request a quote for larger volumes. On budget, on time, every time.
