n-ethylmorpholine

N-Ethylmorpholine (CAS 100-74-3), commonly abbreviated as NEM, is a tertiary amine used as a catalyst and pH-regulating agent across specialty chemical manufacturing. It functions as a reactive intermediate and process catalyst. This chemical serves as a solvent in systems where controlled basicity and miscibility with polar media are required. In polyurethane production, NEM acts as a blowing and gelation catalyst, influencing foam cell structure.

It is used in both flexible and rigid foam formulations to manage the cure rate effectively. Coatings and resin manufacturers use it as a neutralizing amine to stabilize waterborne systems and adjust pH levels. The compound is particularly useful in acrylic and alkyd dispersions. Pharmaceutical synthesis relies on NEM as a non-nucleophilic base and reaction solvent in multi-step organic processes where selectivity is critical.

Mild basicity makes it an ideal choice for sensitive chemical reactions. In metalworking fluids and lubricant concentrates, it functions as a corrosion inhibitor component and an effective emulsion stabilizer. N-Ethylmorpholine is supplied as a clear liquid, typically in drum and IBC quantities for industrial buyers. Technical grade is the standard commercial offering for most large-scale manufacturing applications.

High-purity grades are available for pharmaceutical and fine chemical applications. Specifications vary by supplier, with purity levels commonly at 99% or above for process-critical uses in various industries.
