Description

D-Octamannuronic Acid Octasodium Salt is a well-defined, high-purity oligosaccharide derivative derived from alginate. This compound matters as a critical biochemical tool and reference standard for research into carbohydrate chemistry, enzymology, and the structure-activity relationships of alginate polymers. It is primarily needed by research institutions, pharmaceutical development labs, and biotechnology companies focused on glycoscience, drug delivery systems, and the development of novel biomaterials.

Application

• Biochemical Research: Serves as a precise substrate or standard for studying alginate lyase enzymes, mannuronan C-5-epimerases, and other carbohydrate-active enzymes.
• Pharmaceutical Development: Used as a model compound for investigating the biological activity, bioavailability, and metabolic pathways of alginate-derived oligomers.
• Glycoscience & Structural Analysis: Acts as a critical reference material for nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry to validate analytical methods.
• Biomaterial Precursor: Explored for the synthesis of tailored hydrogels, microcapsules, or scaffolds with specific mechanical and biological properties.
• Standards & Calibration: Provides a high-purity standard for quality control in the production of alginate-based products and for regulatory submissions.

Quality Control

Our D-Octamannuronic Acid Octasodium Salt is produced under stringent conditions to ensure batch-to-batch consistency and high purity, suitable for demanding research applications. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles. We adhere to rigorous internal quality standards and can support development work requiring traceable reference materials.

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 material is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use to prevent absorption of atmospheric moisture, which can affect stability and purity.
