1.It can be used as a plant growth agent, diluted and sprayed on radish leaves, outdoor lawns or other plants to improve the growth and development of plants.
2.Synthesis of methy 2,3,4,6-tetra-O-benzyl-α-D-mannopyranoside, and then synthesis of pharmaceutical intermediate such as 2,3,4,6-tetra-O-benzyl-α-D-mannopyranose.
3.Synthesis of mannopyranoside esters as antimicrobial agents.
4.Selective synthesis of 4,6-O-benzylidene of methyl α-D-mannopyranoside with 2,6-dimethylbenzaldehyde.
5.Surface engineering of solid lipid nanopatticle assemblies for the active targeting to macrophages in anti-tuberculosis inhalation.
6. Partial neopentyl acylation, intramolecular migration and enzymolysis can be performed.
7.Reactivity to release microencapsulated glucoamylase.
8. Synthesis of novel σ-receptor ligands.
9. It forms a sodium vanadate (V) complexes with methyl α- and β-D - galactopyranoside, and select O-methyl derivatives: a 51V and 13C NMR study.
10.Synthesis of L-chiro-inositol-1,2,3-trisphosphate and -1,2,3,5-tetrakisphosphate by ferrier reaction.
11. Synthesis of 2,3-di-O-glycosyl derivatives with methyl α-L-rhamnopyranoside.
12. Partial tosylation of methyl α-D-mannopyranoside.
13.Interaction of vicia faba lectin and methyl α-D-mannopyranoside was investigated by ultraviolet difference spectroscopy. The capacity of lectins to bind specifically to various carbohydrates makes them useful for the isolation and structural analysis of such glycoconjugates as membrane receptors .
14.Partial methylated derivatives were prepared with methyl α-D-galactopyranoside.
15. Chiral building blocks with methyl α-D - glucopyranoside for anthracyclinone synthesis.
