Description

Cellobiouronic Acid is a specific, high-purity disaccharide derivative of glucuronic acid, serving as a crucial biochemical building block and research standard. This compound matters for its role as a defined structural unit in the study of complex polysaccharides like pectin and hemicellulose, enabling precise analytical and synthetic applications. It is primarily needed by researchers and manufacturers in the life sciences, pharmaceutical development, and specialty chemical synthesis sectors who require well-characterized carbohydrate intermediates.

Application

• Biochemical Research Standard: Used as a high-purity reference compound for calibrating analytical instruments (HPLC, MS) and developing assays for carbohydrate analysis.
• Enzymology Studies: Serves as a specific substrate for investigating the activity and kinetics of enzymes like β-glucuronidases and polysaccharide lyases.
• Glycobiology & Pharmaceutical Development: Acts as a key intermediate in the synthesis of more complex glycoconjugates, oligosaccharides, and potential drug candidates targeting carbohydrate-mediated processes.
• Polysaccharide Structure Analysis: Employed in structural elucidation studies of pectins, algal polysaccharides, and bacterial exopolysaccharides where glucuronic acid units are present.
• Specialty Chemical Synthesis: Provides a chiral starting material or building block for the synthesis of novel surfactants, chelating agents, or functional polymers.

Quality Control

Our Cellobiouronic Acid is produced under a strict quality management system to ensure batch-to-batch consistency and reliability for research and development. Each lot undergoes comprehensive analytical testing, including identification by spectroscopic methods and purity assessment by chromatography. A Certificate of Analysis (COA) detailing specific results for purity, identity, and related substances is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent absorption of water. For long-term storage, consider desiccants or inert atmosphere.
