Description

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.

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).
