Application

Triethylamine has been used during the synthesis of:
• 5′-dimethoxytrityl-5-(fur-2-yl)-2′-deoxyuridine
• 3′-(2-cyanoethyl)diisopropylphosphoramidite-5′-dimethoxytrityl-5-(fur-2-yl)-2′-deoxyuridine
• polyethylenimine600-β-cyclodextrin (PEI600-β-CyD)
It may be used as a homogeneous catalyst for the preparation of glycerol dicarbonate, via transesterification reaction between glycerol and dimethyl carbonate (DMC).

General description

Triethylamine (TEA, Et3N) is an aliphatic amine. Its addition to matrix-assisted laser desorption/ionization (MALDI) matrices affords transparent liquid matrices with enhanced ability for spatial resolution during MALDI mass spectrometric (MS) imaging. A head-space gas chromatography (GC) procedure for the determination of triethylamine in active pharmaceutical ingredients has been reported. The viscosity coefficient of triethylamine vapor over a range of density and temperature has been measured.

Determination of Water Content in Triethylamine Using Karl Fischer Titration

Nitrogen compounds, acid amides and weakly basic amines (heterocyclenes) give no problems. They can be titrated according to the standard procedures. Strongly basic amines alter the pH value and must...
