n-Ethylisopropylamine

N-Ethylisopropylamine (CAS 19961-27-4, EC 243-442-1), also known as isopropylethylamine, ethylisopropylamine, and NSC 165659, is a secondary aliphatic amine with the molecular formula C5H13N. It carries no assigned E-code and is classified under HS code 29221990 within the amines category.

In pharmaceutical synthesis, N-ethylisopropylamine functions as a non-nucleophilic base, neutralising acid byproducts during coupling reactions without interfering with electrophilic intermediates. In polymer chemistry, it acts as a polymerization initiator and pH buffer, controlling chain-growth conditions. Agricultural formulation chemists also employ it as a carrier solvent to stabilise active ingredient concentrations.

N-Ethylisopropylamine is supplied as a reagent-grade liquid and falls under REACH registration requirements for commercial quantities within the EU. Procurement teams should confirm supplier SDS documentation and purity specifications prior to ordering. Standard packaging formats include drums and intermediate bulk containers, with quantities available for both laboratory and industrial-scale procurement.
