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.[1] A head-space gas chromatography (GC) procedure for the determination of triethylamine in active pharmaceutical ingredients has been reported.[2] The viscosity coefficient of triethylamine vapor over a range of density and temperature has been measured.[3]
• Application: Triethylamine has been used during the synthesis of:5′-dimethoxytrityl-5-(fur-2-yl)-2′-deoxyuridine[4]3′-(2-cyanoethyl)diisopropylphosphoramidite-5′-dimethoxytrityl-5-(fur-2-yl)-2′-deoxyuridine[4]polyethylenimine600-β-cyclodextrin (PEI600-β-CyD)[5]It may be used as a homogeneous catalyst for the preparation of glycerol dicarbonate, via transesterification reaction between glycerol and dimethyl carbonate (DMC).[6]
