Description
N-Butylamine (CAS 109-73-9, EC 203-699-2), also known as 1-Butanamine or simply Butylamine, is a primary aliphatic amine with the molecular formula C4H11N. It carries no assigned E-code and is classified under HS code 29221980 within the amines category.
In food and flavoring applications, N-Butylamine acts as a flavorant by contributing characteristic amine notes and serves as an acidulant for pH adjustment in formulations. In polymer and coatings manufacturing, it functions as a crosslinker by reacting with epoxy or isocyanate groups to form covalent network structures, accelerating cure and improving mechanical properties.
N-Butylamine is supplied in technical and high-purity grades compliant with REACH registration requirements for the European market. It is available in standard bulk liquid formats including drums and IBCs. Procurement teams should confirm grade specifications against FCC or internal quality standards depending on the intended application.
