Description

D-Rhamnose is a naturally occurring deoxy sugar, specifically the D-enantiomer of rhamnose, with the CAS registry number 634-74-2. This monosaccharide is a valuable chiral building block and biochemical intermediate, prized for its role in the synthesis of complex carbohydrates, glycoconjugates, and specialized fine chemicals. It is essential for research and production in the pharmaceutical, biotechnology, and nutraceutical industries, where it is used to develop novel therapeutics, diagnostic agents, and high-value bioactive compounds.

Application

• Pharmaceutical Intermediate: A key starting material for the synthesis of antibiotics, antiviral drugs, and other active pharmaceutical ingredients (APIs) that require specific sugar moieties.
• Biochemical Research: Used as a standard, substrate, or precursor in enzymatic studies, metabolic pathway analysis, and glycobiology research.
• Glycoconjugate Synthesis: Serves as a crucial building block for creating oligosaccharides, glycolipids, and glycoproteins for vaccine development and diagnostic tools.
• Flavor & Fragrance Industry: Employed in the production of certain flavoring agents and aroma compounds due to its specific stereochemistry.
• Cosmetic Ingredients: Utilized in the formulation of advanced skincare and cosmetic products for its potential moisturizing and bioactive properties.
• Standards and Calibration: Acts as a high-purity analytical standard for chromatography (HPLC, GC) and spectroscopy in quality control laboratories.

Quality Control

Our D-Rhamnose is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity, optical rotation verification, and identity confirmation (IR, NMR), to ensure it meets exacting standards for research and industrial use. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee traceability, consistency, and compliance with your project requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic nature, store in a cool, dry place at a controlled room temperature (15-25°C). For long-term storage, consider desiccated conditions to maintain stability and prevent moisture uptake.
