Triethylamine as a Versatile Organic Base
Triethylamine (TEA, CAS 121-44-8) is a strong tertiary amine base used to scavenge acid in acylation, alkylation and condensation reactions. It is indispensable in pharmaceutical and agrochemical synthesis, and acts as a catalyst in polyurethane foam production and as a curing agent in foundry resins.
