Ethylamine hydrochloride

Ethylamine Hydrochloride (CAS 557-66-4), also known as Ethylammonium Chloride, Monoethylamine HCl, or Ethylamine HCl, is the hydrochloride salt of monoethylamine. It carries no assigned E-code and is classified under HS code 29221980 within the aliphatic amine salts category.

In polymer and coatings formulations, it functions as a cross-linking agent by providing reactive amine groups that form covalent bonds within polymer networks, improving structural integrity and chemical resistance. In textile and leather processing, it acts as an antimicrobial and flame-retardant intermediate, where its ionic character supports compatibility with aqueous treatment baths.

Ethylamine Hydrochloride is supplied as a white to off-white crystalline solid, compliant with REACH registration requirements for the European market. Procurement teams should confirm grade specifications against application requirements, as purity levels vary between technical and reagent grades. Standard packaging formats include fiber drums and multi-layer bags.
