4-nitrophenyl 2,3,4,6-tetra-O-acetyl-beta-D-glucopyranoside

Description:

4-Nitrophenyl 2,3,4,6-tetra-O-acetyl-beta-D-glucopyranoside is a chemical compound that serves as a glycoside derivative of glucose, characterized by the presence of a nitrophenyl group and multiple acetyl groups. This compound features a beta-D-glucopyranoside structure, indicating that the glucose moiety is in its cyclic form and that the anomeric hydroxyl group is in the equatorial position. The acetylation of the hydroxyl groups at positions 2, 3, 4, and 6 enhances the compound's lipophilicity and stability, making it useful in various biochemical applications, particularly in glycosylation reactions and as a substrate in enzymatic assays. The nitro group contributes to the compound's reactivity and can be utilized in spectroscopic studies. Additionally, this compound is often employed in synthetic organic chemistry and biochemistry for the study of glycosidases and other carbohydrate-active enzymes. Its CAS number, 17042-39-6, allows for easy identification in chemical databases and literature.
