Suzhou Pharmaceutical Technology Co., Ltd. (China) supplies N-Methylpyrrolidone CAS 872-50-4 for pharmaceutical B2B procurement — COA, MSDS, and technical documentation available on request.
> Product Overview
N-Methylpyrrolidone (NMP, CAS 872-50-4) is a polar aprotic process solvent used in organic synthesis, polymer processing, and technical development work where buyers need controlled solvent quality, COA/MSDS documentation, and reliable export coordination. Suzhou Pharmaceutical Technology Co., Ltd. supports NMP sourcing for B2B evaluation, process screening, and commercial procurement programs.
This page is written as a procurement and technical reference for solvent buyers. Final use, residual-solvent control, worker protection, and local regulatory decisions remain the responsibility of the buyer's qualified technical and EHS teams.
> Applications and Technical Reference
NMP is selected when a process needs a high-boiling, water-miscible, polar aprotic solvent with strong dissolving power for many organic substrates and polymers. It is commonly discussed for reaction media, purification steps, polymer solution handling, coatings, and specialty process development.
Camp et al., 2010, Green Chemistry, 12, 1430-1436, DOI: 10.1039/C004659A, reported biobased N-methylpyrrolidone synthesis with n=1 process route. We cite this as technical literature background only, not as a product performance or regulatory claim.
