Description

2,3-Dialdehydocellulose is a chemically modified cellulose derivative where specific hydroxyl groups are oxidized to aldehyde functionalities. This modification is critical as it imparts unique reactivity, enabling the material to act as a versatile cross-linking agent and platform for further chemical synthesis. It is primarily sought after by researchers and manufacturers in the fields of biomedical engineering, advanced material science, and specialty chemical production for developing hydrogels, drug delivery systems, and functional polymers.

Application

• Cross-linking agent for the synthesis of biodegradable hydrogels and scaffolds in tissue engineering.
• Functional intermediate for creating drug delivery carriers with controlled release profiles.
• Precursor for the development of chelating resins and adsorbents for water treatment and metal recovery.
• Reactive substrate for immobilizing enzymes, antibodies, or other biomolecules in biosensor and diagnostic applications.
• Starting material for the production of specialty cellulose-based polymers with enhanced mechanical or chemical properties.
• Component in the formulation of advanced coatings and films with tailored surface characteristics.

Quality Control

Our 2,3-Dialdehydocellulose is produced under a rigorous quality management system. Each batch is characterized to ensure consistent aldehyde content, degree of polymerization, and purity. Comprehensive testing includes identification, assay, and residual analysis. A Certificate of Analysis (COA) detailing all specifications and test results is provided with every shipment to guarantee traceability and compliance with your research or production standards.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic and easily oxidized nature, store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place at 2-8°C for long-term stability. Allow the sealed container to equilibrate to room temperature before opening to minimize moisture ingress.
