Description

.Beta.-D-Gulopyranose, 1,6:2,3-Dianhydro-4-o-(Phenylmethyl)- is a specialized anhydro sugar derivative, serving as a crucial chiral building block and synthetic intermediate in advanced organic chemistry. Its value lies in its rigid, bicyclic structure and protected hydroxyl group, which enable precise stereochemical control in the synthesis of complex molecules. This compound is essential for researchers and manufacturers in the pharmaceutical and fine chemical industries, particularly for developing novel active pharmaceutical ingredients (APIs), nucleoside analogs, and carbohydrate-based therapeutics.

Application

• Pharmaceutical Intermediate: Key chiral synthon for the research and production of nucleoside-based antiviral and anticancer drugs.
• Carbohydrate Chemistry Research: Used in academic and industrial R&D to study glycosylation reactions and synthesize complex oligosaccharides.
• Fine Chemical Synthesis: Building block for creating specialty chemicals, flavors, fragrances, and advanced materials requiring specific stereochemistry.
• Glycoconjugate Development: Intermediate in the synthesis of glycoconjugates for diagnostic tools and vaccine development.
• Process Chemistry: Employed in route scouting and scale-up processes for new chemical entities (NCEs) in GMP and non-GMP environments.

Quality Control

Our .Beta.-D-Gulopyranose, 1,6:2,3-Dianhydro-4-o-(Phenylmethyl)- is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, chiral analysis, and identity confirmation (IR, NMR), to ensure it meets the stringent requirements for pharmaceutical R&D and fine chemical synthesis. Certificates of Analysis (COA) with detailed chromatographic data are provided for every shipment, ensuring full traceability and compliance with your internal specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture. For long-term storage, consider using desiccants.
