2,3,4,6-Tetra-O-acetyl-D-glucopyranose

2,3,4,6-O-四乙酰基-D-葡萄糖,

2,3,4,6-Tetra-O-acetyl-beta-D-glucopyranose is a synthetic compound that is used as an oral medicine. It has been shown to be effective in the treatment of arthritis and other inflammatory conditions. The preparation process involves the conversion of 2,3,4,6-tetra-O-acetyl-beta-D-glucopyranose into besifloxacin and chiral 2,3,4,6 tetra acetyl beta D glucopyranose. This drug is then recrystallized with potassium carbonate to produce besifloxacin as a white crystalline solid. Recrystallizing this drug produces besifloxacin as a white crystalline solid. 2,3,4,6 Tetra O Acetyl Beta D Glucopyranose can be detected using analytical chemistry methods such as reversed phase liquid.
