1-(2-Aminoethyl)-2-imidazolidinone

1-(2-Aminoethyl)-2-imidazolidinone (CAS 6281-42-1, EC 228-491-9) is a cyclic urea derivative carrying a primary amine side chain, commercially known under names including N-(2-Aminoethyl)ethyleneurea and BUTTPARK 52\06-90. It carries no assigned E-code and is catalogued under HS code 29332900.

In textile and paper finishing, the compound reacts with cellulose hydroxyl groups through its cyclic urea moiety, functioning as a durable press cross-linking agent that improves dimensional stability. In water treatment and polymer formulations, the primary amine group participates in curing epoxy networks and coordinates metal ions, enabling both chelation of heavy metals and controlled polymerization initiation.

This material is supplied as a neat viscous oil and is registered under REACH. Procurement teams should confirm supplier documentation including Safety Data Sheets and certificate of analysis for purity and amine content.
