General description

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.[1] Mechanism of pertraction of MPCA through layered bulk liquid membranes has been studied.[2] MPCA reacts with Ln(NO3)3·6H2O and K4[W(CN)8]·2H2O to form unique three-dimensional network structure which contains open channels.[3]

Application

5-Methyl-2-pyrazinecarboxylic acid may be used in the preparation of novel europium(III) complexes, (5-methyl-2-pyrazinecarboxylato) (phenanthroline)europium(III).[4] It may be used in the synthesis of Ln-metal organic frameworks (MOFs).[5]

    Over four decades ago, in vitro experiments showed that tau protein interacts with and stabilizes microtubules in a phosphorylation-dependent manner. This observation fueled the widespread hypotheses that these properties extend to living neurons and that reduced stability of microtubules represents
