DESCRIPTION
General description
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. Application 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. Packaging This product is also available in glass bottles. Other Notes 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. |
