Product Profile
Tri-n-Butylamine (TNBA), also known as Tributylamine, is a high-purity tertiary aliphatic amine widely used as a catalyst, chemical intermediate, and precursor for phase transfer catalysts in the production of pharmaceuticals, agrochemicals, specialty chemicals, and quaternary ammonium compounds.
It is a clear, colorless liquid with a characteristic amine odor and may gradually develop a pale yellow coloration during prolonged storage. Tri-n-Butylamine is sparingly soluble in water but highly soluble in alcohols, ethers, and many organic solvents, making it an effective reagent for a variety of industrial synthesis processes.
