Description

D-Dimannuronic Acid Disodium Salt is a high-purity, water-soluble derivative of mannuronic acid, a key uronic acid monomer. This compound is valued for its role as a critical building block and standard in the research and synthesis of complex polysaccharides, particularly alginates. It is essential for researchers and manufacturers in the pharmaceutical, biotechnology, and advanced materials sectors who require precise, high-quality intermediates for product development and quality control.

Application

• Biochemical Research Standard: Used as a certified reference material for the analysis and characterization of alginate polymers and other mannuronic acid-containing biomolecules.
• Pharmaceutical Intermediate: Serves as a key starting material or precursor in the synthesis of novel drug candidates, especially those targeting carbohydrate-protein interactions.
• Enzyme Substrate: Acts as a specific substrate for studying the activity of enzymes like mannuronan C-5-epimerases, which are involved in alginate modification.
• Nutraceutical & Cosmetic Development: Employed in R&D for formulating advanced functional ingredients derived from marine polysaccharides.
• Material Science: Used in the development of hydrogels, biocompatible coatings, and other smart materials where alginate structure-property relationships are being engineered.
• Quality Control: Essential for analytical laboratories to calibrate instruments and validate methods for purity assessment of alginate-based products.

Quality Control

Our D-Dimannuronic Acid Disodium Salt is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via NMR and IR spectroscopy, to ensure it meets the high standards required for research and production. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting batch-specific results.

Storage

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