Description

D-Erythro-Pent-4-Enose, 4,5-Dideoxy-2,3-o-(1-Methylethylidene)- (9Ci) is a specialized carbohydrate derivative and a protected sugar intermediate of significant interest in synthetic organic chemistry. This compound matters for its role as a key chiral building block, enabling the stereoselective synthesis of complex molecules. It is primarily needed by research institutions and pharmaceutical companies engaged in the development of nucleoside analogs, antiviral agents, and other bioactive compounds where precise sugar scaffold manipulation is critical.

Application

• Pharmaceutical Intermediate: Serves as a crucial chiral precursor in the synthesis of novel nucleoside and nucleotide analogs for antiviral and anticancer research.
• Glycochemistry Research: Used as a protected sugar synthon for constructing complex oligosaccharides, glycoconjugates, and glycomimetics.
• Chemical Biology Probes: Employed in the development of labeled or modified sugars to study carbohydrate-protein interactions and metabolic pathways.
• Asymmetric Synthesis: Acts as a chiral pool starting material or auxiliary for the stereocontrolled construction of natural products and fine chemicals.
• Process Development: Utilized in scaling up synthetic routes for active pharmaceutical ingredients (APIs) that require specific sugar-derived motifs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
