Description

N,N'-Diethylethylenediamine CAS NO 111-74-0 is a versatile diamine compound featuring two tertiary amine groups separated by an ethylene bridge. This structure makes it a valuable intermediate and catalyst in organic synthesis and polymer chemistry. It is primarily utilized by manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries for applications requiring a strong, sterically hindered organic base or a chelating ligand.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs), particularly for drugs requiring complex amine functionalities.
• Catalyst & Ligand: Serves as a ligand for metal catalysts in cross-coupling reactions and as an organic base catalyst in various organic transformations.
• Polymer Industry: Acts as a curing agent for epoxy resins and a monomer or chain extender in the production of polyamides, polyurethanes, and other specialty polymers.
• Agrochemical Synthesis: Employed as a key building block in the manufacture of herbicides, fungicides, and plant growth regulators.
• Corrosion Inhibitor Formulation: Used in the production of additives for fuels and lubricants due to its chelating and basic properties.
• Chelating Agent: Functions as a complexing agent for metal ions in analytical chemistry and industrial processes.
