Overview

N,N-diethylethanamine (CAS 121-44-8) is a tertiary aliphatic amine with strong basic properties and high reactivity. This organic compound, also known as triethylamine, represents one of the most widely used tertiary amines in industrial chemistry due to its excellent catalytic and neutralizing capabilities. With the molecular formula C6H15N and a molecular weight of 101.19 g/mol, this colorless liquid exhibits characteristic amine properties including a distinctive fishy odor and high volatility. The compound's tertiary structure, where three ethyl groups are attached to a central nitrogen atom, confers unique chemical properties that distinguish it from related compounds like N',N'-diethylpropane-1,3-diamine, which contains primary amine functionality alongside tertiary amine groups. Safety considerations are paramount when handling N,N-diethylethanamine, as it carries multiple hazard classifications including Flammable Liquid Category 2, Acute Toxicity Category 3, Skin Corrosion Category 1A, and Eye Damage Category 1. The substance requires careful storage away from ignition sources and oxidizing agents, with appropriate personal protective equipment mandatory during handling. Its ADR Class 3 classification reflects its flammable nature, necessitating specialized transport protocols. Industrial applications leverage the compound's strong basicity and nucleophilic properties. It serves as an essential catalyst in polyurethane foam production, facilitating the reaction between isocyanates and polyols. The pharmaceutical industry utilizes it as a base in various synthetic processes, while it also functions as a pH regulator and intermediate in agrochemical manufacturing. OYSI provides reliable access to high-quality N,N-diethylethanamine for European industrial customers, supporting diverse applications across multiple sectors with comprehensive technical documentation and regulatory compliance assurance.
