Description

Chitobiose Octaacetate is a fully acetylated derivative of the chitobiose disaccharide, a fundamental building block of chitin and chitosan polymers. This high-purity chemical intermediate is critical for researchers and manufacturers requiring precise, well-defined oligosaccharide structures for advanced applications. It serves as an essential starting material in the synthesis of bioactive glycoconjugates, novel polymers, and specialized reagents for the pharmaceutical, biotechnology, and advanced materials sectors.

Application

• Glycochemistry & Glycobiology Research: A key precursor for the chemical and enzymatic synthesis of complex oligosaccharides, glycopeptides, and glycomimetics used in structure-activity relationship studies.
• Pharmaceutical Intermediate: Used in the development of drug delivery systems, prodrugs, and therapeutic agents that target carbohydrate-binding proteins or modulate immune responses.
• Bioconjugation & Probe Development: Serves as a versatile scaffold for creating fluorescent, affinity, or bioactive tags for labeling proteins, cells, and other biomolecules.
• Polymer Science: Acts as a monomer or co-monomer for creating novel, biodegradable polymers with tailored properties for medical devices, tissue engineering, and specialty coatings.
• Enzymology Studies: Employed as a standard substrate or inhibitor for studying the activity and kinetics of chitinases, chitosanases, and other glycosyl hydrolases.
• Standards & Calibration: Provides a high-purity reference standard for analytical methods (HPLC, MS, NMR) in quality control and research laboratories.

Quality Control

Our Chitobiose Octaacetate is produced under strict quality management protocols. Each batch undergoes comprehensive analytical characterization, including HPLC for purity, NMR and MS for structural confirmation, and tests for residual solvents and moisture to ensure it meets the stringent requirements of research and process development. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting the specific results for your quality assurance records.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use to prevent absorption of atmospheric moisture, which may affect stability and performance.
