一般描述

Methanol is an alcohol. Its conversion to C2-C10 hydrocarbons by employing a new class of shape-selective zeolites has been reported. Its oxidation on Ru-Pt catalyst system by ruthenium ad-atoms has been proposed.

应用

Methanol was 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.

包装

本品也提供玻璃瓶包装。

其他说明

The article number 24229-4X2.5L-R will be discontinued. Please order the single bottle 24229-2.5L-R which is physically identical with the same exact specifications.
