n-formylmorpholine

N-Formylmorpholine (CAS 4394-85-8), abbreviated NFM, is a polar aprotic solvent.

Where is n-formylmorpholine used?

• Pharmaceutical manufacturing: reaction solvent
• Active ingredient synthesis: carrier where low volatility and chemical inertness are required
• Polymer processing: dissolves and spins aromatic polyamides for fiber and membrane lines
• Industrial cleaning: heavy-duty degreasers for resins, coatings and adhesive residues
• Specialty chemical synthesis: controlled polarity supports high reaction yields
• It also serves as a catalyst solvent.

Good to know: High-purity grades meet pharmaceutical and specialty chemical specifications; technical grade is standard for most industrial use. Buyers should confirm purity thresholds and water content limits against internal process requirements.

Commercial specifications

• Intermediate packaging: drums and IBCs
• Purity thresholds and water content limits to verify when sourcing
