Application: | Diethylamine has been used to constitute the extraction solvent mixture for the gas chromatography-mass spectrometric (GC-MS) analysis of melamine and related compounds. It has been also been used as a bond breaking agent in a novel ELISA technique to measure the avidity index (AI) of IgG-anti-PT (Immunoglobulin G-anti-pertussis toxin) antibodies. It may be used as: • An organocatalyst for the preparation of β-phosphonomalononitriles and diethyl (2-amino-3- cyano-chromene-4-yl) phosphonic acid esters. • A ligand for the synthesis of (N-heterocyclic carbene)PdCl2(diethylamine) complexes. • A template for the preparation of thermally and hydrothermally stable SAPO-34 (silicoaluminophosphate) molecular sieves. |
General description: | Diethylamine (DEA) is an organic base and a weak σ-donor ligand. |
