1,3,5-Tri-O-acetyl-2-deoxy-D-erythro-pentofuranose

It often serves as a key intermediate in nucleoside synthesis, particularly for preparing deoxyribonucleoside analogs. The acetyl protecting groups enhance stability and allow selective functionalization during chemical transformations. 1,3,5-Tri-O-acetyl-2-deoxy-D-erythro-pentofuranose is a protected 2-deoxypentose sugar in which the hydroxyl groups at positions 1, 3, and 5 are acetylated.
