Triethylamine

Triethylamine (CAS 121-44-8) is a tertiary amine commonly abbreviated as NEt3 or written as (C2H5)3N. It carries no E-code designation and is also referenced under the names triethyl amine and N,N,N-triethylamine. It is classified under HS code 29221910 and falls within the broader amines category.

In pharmaceutical manufacturing, triethylamine functions as a base catalyst and acid scavenger, neutralizing HCl generated during synthesis to drive reactions toward completion. In polymer production, it acts as a catalyst in polyurethane and polymerization processes. It also finds application as an antimicrobial agent and flavorant in food-adjacent formulations.

Triethylamine is supplied as a liquid and is available in technical and high-purity grades suited to pharmaceutical and industrial applications. Procurement teams should verify compliance with REACH regulations and confirm grade suitability against Ph.Eur. or FCC standards depending on end use. Standard packaging includes drums and IBCs for bulk orders.
