설명

일반 설명

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.

애플리케이션

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).
