Nmp Excellent872-50-4

Nmp Excellent872-50-4 (N-Methyl-2-pyrrolidone, CAS 872-50-4) is an ultrapure aprotic solvent (≥99.95% GC).Engineered for critical electronics/pharma processes requiring <10 ppm water content.

Colorless transparent oily liquid with a slight amine odor. It is miscible with water, alcohols, ethers, esters, ketones, halogenated hydrocarbons, aromatics and castor oil. Low volatility, good thermal and chemical stability, and volatilization with water vapor. It is hygroscopic. Sensitivity to light. It is a polar aproton transport solvent with the advantages of low toxicity, high boiling point, outstanding solubility, strong selectivity and good stability.

 

 

 

 

 

The chemical properties of this product are not active, except for copper, it is non-corrosive to other metals such as carbon steel and aluminum. It is packed in galvanized iron drums, stored and transported according to general chemical regulations, and the net weight is 200kg/drum. ISOTANK tank for bulk.

 

▲Li-ion battery electrolytes: Solvent for LiPF₆/LiFSI salts (H₂O ≤5ppm)

▲Photoresist stripping: Semiconductor wafer cleaning (metals ≤0.1ppm)
