Overview

N'-[2-[2-(2-aminoethylamino)ethylamino]ethyl]ethane-1,2-diamine (CAS 112-57-2) is a pentaethylenehexamine polyamine compound with strong chelating properties and multiple reactive amino groups. This linear polyamine, also known by its molecular formula C8H23N5, represents an important class of aliphatic polyamines widely used in industrial chemistry. With a molecular weight of 189.3 g/mol, this compound features five nitrogen atoms connected by ethylene bridges, creating a highly versatile molecule with excellent metal-binding capabilities and strong alkaline properties. The multiple amino groups provide exceptional reactivity, making it valuable for various chemical processes including metal chelation, polymer crosslinking, and surface treatment applications. The compound exhibits significant safety considerations, classified under GHS pictograms GHS05, GHS07, and GHS09, with a danger signal word. It presents acute toxicity (Category 4), skin corrosion (1B), and skin sensitization properties, requiring careful handling with appropriate personal protective equipment. Its ADR Class 8 classification indicates corrosive transport requirements. Environmental precautions are necessary due to its Aquatic Chronic 2 classification. Primary industrial applications include use as a chelating agent in metal processing, as a curing agent for epoxy resins, and in water treatment formulations. Unlike simpler compounds such as N-cyclohexylcyclohexanamine, this polyamine's multiple coordination sites enable superior performance in complex metal ion sequestration. It also serves as an intermediate in the synthesis of specialized polymers and surface-active agents. The compound finds particular value in industries requiring robust metal complexation or where multiple reactive sites are advantageous for crosslinking applications. OYSI maintains reliable supply capabilities for this technical-grade polyamine to serve European industrial customers.
