N-Methyl-2-pyrrolidone is a high-polarity aprotic solvent with excellent dissolving capacity and chemical stability, widely used in fine chemical, pharmaceutical, electronic and polymer industries. It serves as a key solvent for lithium-ion battery electrode manufacturing, polymer spinning, resin synthesis and plastic processing. In pharmaceutical industry, it is applied as reaction solvent and extraction medium for drug intermediate synthesis and raw material purification. It also acts as a stripping agent, cleaning agent and carrier solvent in electronic wafer cleaning, industrial degreasing and pesticide formulation. Moreover, it is commonly used in laboratory organic synthesis, chromatographic analysis and as a standard reagent for chemical research due to its low volatility and strong solvency for polar and non-polar compounds.

This chemical may cause irritation to skin, eyes and respiratory tract upon direct contact or inhalation. Prolonged skin exposure may lead to dryness, redness and allergic discomfort; eye contact results in stinging, redness and temporary irritation. Inhalation of vapor may cause dizziness, headache and mild respiratory discomfort, while excessive oral ingestion may bring gastrointestinal upset. Operators should wear chemical resistant gloves, splash goggles and respirator during handling, and keep working environment well ventilated. Store in tightly sealed containers at cool dry dark place, keep away from fire, heat sources and strong oxidizing substances. Waste liquid must be treated by professional hazardous waste disposal procedures, avoid random discharge into water and soil to prevent environmental pollution and cumulative toxic risks to organisms.
