In heterogeneous catalysis, the catalyst is in a different phase from the reactants. At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. In an article, once mentioned the application of 10034-20-5, Name is (2S,3R,4R,5S,6R)-6-(Acetoxymethyl)-3-aminotetrahydro-2H-pyran-2,4,5-triyl triacetate hydrochloride,molecular formula is C14H22ClNO9, is a conventional compound. this article was the specific content is as follows.Electric Literature of 10034-20-5
Mono- and di-N-alkylated derivatives of 1,3,4,6-tetra-O-acetyl-2-amino-2- deoxy-beta-D-glucose (alkyl = methyl, ethyl, propyl, butyl, pentyl, hexyl, benzyl) were synthesised by the reductive alkylation of per-O-acetyl-d- glucosamine. (N-ethyl, N-propyl, N-butyl, N-pentyl and N-hexyl)-1,3,4,6-tetra-O- acetyl-2-amino-2-deoxy-beta-D-glucoses were deacetylated in order to attempt an enzymatic phosphorylation. All products were characterised by means of IR, NMR and MS spectra. N-Ethyl- and N-pentyl-D-glucosamines were found to exhibit weak antifungal activity.
