N-Methyl-2-Pyrrolidone 99.9% (NMP)

N-Methyl-2-Pyrrolidone 99.9% (NMP) (CAS 872-50-4, molecular formula C5H9NO) is a process chemical for electronics and metal finishing, where trace metal content and particle contamination matter as much as headline assay. China Chemicals supplies it at 99.9% min in pack sizes from 1 L through to 200 L Drum, so laboratory trial quantities and full production volumes can be sourced from the same specification.

It is also traded as NMP, 1-Methyl-2-pyrrolidone, M-Pyrol. Every consignment ships with a batch-specific Certificate of Analysis and the current Safety Data Sheet, and material is stored and picked under stock rotation so you receive product well inside its shelf life.

Typical applications

Photoresist stripping in semiconductor fabrication
Binder solvent for lithium battery electrode slurry
Polyimide and engineering polymer processing
Aromatics extraction in petrochemical refining
High-performance paint and coating remover
