Description
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
