Description

D-Mannuronic Acid Sodium Salt is a high-purity sodium salt derivative of mannuronic acid, a key uronic acid monomer. This compound serves as a critical building block and standard in the research and production of alginates and other polysaccharides. It is essential for manufacturers and R&D laboratories in the pharmaceutical, biomedical, and advanced materials sectors requiring precise control over polymer composition and properties.

Application

• Biomedical Research: As a monomeric standard for studying alginate structure, biosynthesis, and enzymatic degradation pathways.
• Pharmaceutical Development: Used in the synthesis and characterization of alginate-based drug delivery systems, hydrogels, and wound dressings.
• Tissue Engineering: A key precursor for creating tailored alginate scaffolds with specific mechanical and biological properties for cell culture and regeneration.
• Food Science: Employed in research to understand and modify the gelling, thickening, and stabilizing properties of alginates in food products.
• Cosmetic Ingredients: Used in the development and quality control of alginate-based cosmetic formulations for their film-forming and moisturizing effects.
• Analytical Reference Standard: Serves as a high-purity calibrant in chromatographic (HPLC, GC) and spectroscopic methods for quantitative analysis.
• Chemical Synthesis: Acts as a starting material or intermediate for the chemical modification and production of novel carbohydrate-based polymers.

Quality Control

Our D-Mannuronic Acid Sodium Salt is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including identification (IR, NMR), purity assay (HPLC), and specific tests for residual solvents and moisture, to ensure it meets the high standards required for research and production. Certificates of Analysis (COA) detailing all specifications and results are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after use to prevent moisture absorption, which can affect stability and handling properties.
