Popis

General description

Ethyl acetate ACS grade solvent meets or exceeds the high standards of the American Chemical Society (ACS). It is ideal for most research needs and delivers replicable, publishable results.
Ethyl acetate ACS grade solvent used in:      

• Routine chemical synthesis      
• Drying & purification     
• Critical labware cleaning

Application

Ethyl acetate (ACS grade) can be used as a solvent in the synthesis of 6-O-acetyl glycosides via selective acetylation of carbohydrates in the presence of a catalytic amount of sulfuric acid. 6-O-acetyl glycoside derivatives are applicable as precursors for the synthesis of complex oligosaccharides.
