Product Introduction

Tridodecylamine (TDDA), also known as Trilaurylamine, identified by CAS 102-87-4, is a high-performance tertiary amine widely utilized in specialty metallurgy and fine chemical synthesis.

Appearing as a colorless to slightly yellowish liquid with the chemical formula C36H75N, TDDA is characterized by its three long 12-carbon alkyl chains. These chains provide the molecule with intense hydrophobic properties and a high boiling point, making it an ideal candidate for solvent extraction (liquid-liquid extraction) processes. It is a critical reagent in the nuclear and precious metals industries for the purification of various elements and is also used as a specialized catalyst and intermediate in organic chemistry.
