产品说明

一般描述

5-Methyl-2-pyrazinecarboxylic acid is a pyrazine derivative. Simultaneous membrane based solvent extraction (MBSE) and membrane based solvent stripping (MBSS) of 5-methyl-2-pyrazine carboxylic acid (MPCA) has been studied. Mechanism of pertraction of MPCA through layered bulk liquid membranes has been studied. MPCA reacts with Ln(NO₃)₃·6H₂O and K₄[W(CN)₈]·2H₂O to form unique three-dimensional network structure which contains open channels.

应用

5-Methyl-2-pyrazinecarboxylic acid may be used in the preparation of novel europium(III) complexes, (5-methyl-2-pyrazinecarboxylato) (phenanthroline)europium(III). It may be used in the synthesis of Ln-metal organic frameworks (MOFs).
