Glucose pentaacetate
1. Basic Information
Name: Glucose pentaacetate
Alias: Penta-O-acetyl-D-glucose
CAS No.: 604-68-2
Molecular Formula: C14H18O9
Molecular Weight: 330.29
Category: Carbohydrate protected intermediate, pharmaceutical raw material, fine chemical synthesis substrate, chromatographic reference standard
2. Physical and Chemical Properties
Physical Properties
- Appearance: White crystalline powder
- Odor: Odorless, faint acetic ester mild smell
- Solubility: Soluble in chloroform, dichloromethane, hot ethanol, acetone; slightly soluble in cold ethanol; insoluble in water, petroleum ether, hexane
- Melting Point: 112–114 ℃
- Specific Rotation [α]D20: +40° ~ +44° (c=5, CHCl3)
- Density (predicted): 1.28 g/cm3
- Hygroscopy: Non-hygroscopic under normal storage environment
- Aqueous property: Stable in neutral cold water; ester groups hydrolyze under strong acid/alkali heating to generate glucose and acetic acid
Chemical Properties
- Molecular structure: All five hydroxyl groups of D-glucose fully acetylated, fully protected sugar derivative with stable six-membered pyranose ring
- Protecting group characteristic: Acetyl groups can be selectively or fully deacetylated under acidic or alkaline conditions to recover glucose hydroxyl groups
- Glycosylation reactivity: Classic raw material for glycosylation reaction, can prepare glycoside, glycosamine and other carbohydrate drug intermediates
- Thermal stability: Stable below 100 ℃; long-time heating above melting point causes partial deacetylation discoloration
- Photostability: Good light resistance, no obvious discoloration under long-term light storage
- Compatibility: Compatible with most anhydrous organic solvents; incompatible with concentrated strong acid, strong alkaline aqueous solution at high temperature
3. Main Application Fields
1. Carbohydrate Pharmaceutical Intermediate (Core Application)
