一般描述

Methanol is an alcohol. Its thermochemical conversion to C2-C10 hydrocarbons in the presence of shape-selective zeolites has been reported. Its oxidation on Ru-Pt catalyst system by ruthenium ad-atoms has been proposed.

应用

Methanol (MeOH) may be used in the following studies:
  • Colony forming unit-fibroblast assay of bone marrow mononuclear cells.
  • As solvent for the preparation of extracts of hyphae of Aspergillus for the estimation of gliotoxin by reversed phase-HPLC.
  • Immunofluorescence studies.
  • To compose eluent for the ion-pair reverse-phase HPLC isolation of nucleotides and their decomposition products.
  • As eluent in the HPLC estimation of malondialdehyde in plasma, which is an indicator of oxidative stress.

其他说明

A -D suffix exists for administrative purposes only.
All -D packages are 100% the same product, same quality, same specification as the package sizes previously sold without a -D.

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.
