2-Diethylethanolamine

2-Diethylethanolamine (CAS 100-37-8), also known as DEAE, is an amino alcohol used in industrial and specialty chemical manufacturing as a pH regulator, corrosion inhibitor, and emulsifier.

Where is 2-Diethylethanolamine used?

• Metalworking and industrial lubricants: neutralizes acidic byproducts in cutting fluids and coolants, extending fluid life and protecting ferrous surfaces from corrosion
• Water treatment: conditions boiler feed water and cooling tower circuits, controlling pH to reduce scale and corrosion in closed-loop systems
• Coatings: neutralizing agent for waterborne resin systems, improving dispersion stability and film formation in architectural and industrial paints
• Pharmaceutical manufacturing: intermediate in the synthesis of active pharmaceutical ingredients, especially compounds requiring an aminoethanol backbone
• Its dual amine-alcohol functionality makes it a building block for synthesizing active compounds and a direct-use additive in formulated products.

Good to know: Technical grade is the standard offering for industrial applications; pharmaceutical-grade material meeting USP or equivalent specifications is available for API synthesis and regulated manufacturing.
