n-formylmorpholine

N-Formylmorpholine (CAS 4394-85-8), commonly abbreviated as NFM, is a polar aprotic solvent used across pharmaceutical synthesis, polymer processing, and industrial cleaning applications. Its high solvating power and thermal stability make it a preferred alternative to more regulated solvents in demanding process environments. In pharmaceutical manufacturing, NFM functions as a reaction solvent.

It is used as a carrier in active ingredient synthesis, particularly where low volatility and chemical inertness are process requirements. Polymer processors use it to dissolve and spin aromatic polyamides. This includes applications in fiber and membrane production lines for engineering polymers. Industrial and institutional cleaning formulators incorporate NFM into heavy-duty degreasers targeting resins and coatings.

It is effective against adhesive residues on industrial equipment and serves as a catalyst solvent. In specialty chemical synthesis, its controlled polarity is critical to achieving high reaction yields. NFM is supplied as a liquid in bulk quantities, with intermediate packaging available in drums and IBCs. Technical grade is the standard commercial offering for most industrial applications.

High-purity grades are available to meet pharmaceutical and specialty chemical process specifications. Buyers should confirm purity thresholds and water content limits against internal process requirements when sourcing.
