Methylglucoside is a monosaccharide derived from glucose. It can be prepared in the laboratory by the acid-catalyzed reaction of glucose with methanol.[2]

It is used as a chemical intermediate in the production of a variety of products including emollients, emulsifiers, humectants, moisturizers, thickening agents, plasticizers, surfactants, varnishes, and resins. The formation of methyl glycoside indicates that the structure of glucose is not open chain.[1][3]
