Is N-Methyl-2-pyrrolidone hazardous?

Yes, N-Methyl-2-pyrrolidone (NMP) is considered hazardous: it can irritate the skin, eyes, and respiratory tract, be absorbed through the skin to affect internal organs, harm reproductive health and fetal development, and is environmentally harmful to aquatic life, leading to its classification as a reproductive toxicant with strict handling and exposure limits in many regions.

When handling N‑Methyl‑2‑pyrrolidone (NMP), wear chemical‑resistant gloves, safety goggles, and protective clothing to prevent skin/eye contact and vapor inhalation; work in well‑ventilated areas, avoid open flames and static buildup, store NMP in tightly sealed containers in cool, dry places away from incompatible materials, clean up spills promptly with inert absorbents, wash thoroughly after use, and follow local regulations for waste disposal and exposure limits.
