1-(2-Aminoethyl)-2-imidazolidinone

CAS: 6281-42-1

Overview

1-(2-Aminoethyl)-2-imidazolidinone (CAS 6281-42-1 ) is a cyclic urea-based amine combining a reactive primary amine with a five-membered imidazolidinone ring. This dual-functional structure positions it as a building block and functional additive.

It is utilized for chelation, surface modification, and pH buffering across multiple industrial sectors. In water treatment formulations, it acts as a chelating agent to sequester metal ions and stabilize treatment chemistry.

Textile and paper processors use it to modify fiber surfaces, improving dye uptake and wet fastness in finishing operations. In coatings and adhesive systems, the primary amine group enables crosslinking with resins.

This contributes significantly to adhesion and film integrity in epoxy or isocyanate systems. Personal care formulators incorporate it as a buffering and conditioning agent in rinse-off and leave-on products.

It is particularly effective in formulations targeting scalp and hair applications. 1-(2-Aminoethyl)-2-imidazolidinone is typically supplied as a liquid or low-melting solid for industrial handling.

Aqueous solution grades are common, while technical grade is the standard commercial offering. Purity specifications generally range from 97% to 99% depending on the supplier and intended application.

Packaging options typically include drums and IBCs for bulk industrial procurement. This versatile chemical intermediate meets rigorous industrial requirements for stability and performance in diverse environments.
