General description

甲醇（MeOH）是一种有机溶剂，具有广泛的工业应用。它是锂电池的主要成分。它可以在各种条件下通过CO2加氢制备。MeOH 是一种使乙醇变性的有毒醇。一项研究报告了在超临界条件下使用甲醇以菜籽油制备生物柴油。

Application

符合ACS规范。
高纯度、多用途溶剂，经测试适用于:
  • HPLC梯度分析
  • 分光光度计
  • 残留测试
  • LC-MS应用

作为溶剂/试剂，测定蜜蜂雄蜂血液匀浆(DBH)样品中的总酚含量、抗DPPH活性和抗氧化剂含量。

This Communication describes the hydrogenation of carbon dioxide to methanol via tandem catalysis with dimethylamine and a homogeneous ruthenium complex. Unlike previous examples with homogeneous catalysts, this CO2-to-CH3OH process proceeds under basic reaction conditions. The dimethylamine is proposed to play

ATP analogs substituted in the gamma-phosphorus (ATPgammaS, beta, gamma-imido-ATP, and beta,gamma-methylene-ATP) were used to probe the involvement of P2 receptors in the modulation of synaptic transmission in the hippocampus, because their extracellular catabolism was virtually not detected in CA1 slices.
