Applications of 22352-19-8
| Industry | Application | Process |
|---|---|---|
| Organic Synthesis | Protecting reagent for maltose hydroxyl groups in carbohydrate chemistry | Acetylation protection conducted under anhydrous conditions using pyridine as solvent and acetic anhydride as reagent, enabling subsequent selective deprotection or glycosylation reactions |
| Pharmaceutical R&D | Intermediate for carbohydrate-based drug synthesis, including antidiabetic or antibacterial candidate compounds | Selective deacetylation yields maltose derivatives, which are then employed in glycosidic bond formation or structural modification |
| Analytical Chemistry | Derivatization standard for maltose in gas chromatography–mass spectrometry (GC–MS) analysis | Acetylation enhances maltose volatility and thermal stability to facilitate GC separation and quantitative detection |
