Description

D-Trimannuronic Acid Trisodium Salt is a well-defined, high-purity oligosaccharide derivative of alginic acid, a key polysaccharide found in brown seaweed. This compound is valued for its specific chemical structure and ionic properties, making it a crucial intermediate and reference standard in advanced biochemical research and development. It is primarily utilized by researchers and manufacturers in the pharmaceutical, cosmetic, and nutraceutical industries for applications ranging from drug delivery systems to bioactive ingredient synthesis.

Application

• Pharmaceutical Research: As a reference standard or intermediate in the development of novel drug delivery vehicles, particularly for studying carbohydrate-protein interactions and controlled release mechanisms.
• Biochemical Studies: Used in enzymatic assays and as a substrate to investigate the activity of alginate lyases and other carbohydrate-active enzymes.
• Cosmetic Science: Serves as a model compound for developing and testing new bioactive ingredients with moisturizing, anti-inflammatory, or skin-barrier enhancing properties.
• Nutraceutical Development: Employed in research focused on the bioactivity of alginate-derived oligosaccharides, exploring potential prebiotic or immunomodulatory effects.
• Material Science: Investigated as a building block for creating novel biodegradable hydrogels, films, and polymers with tailored ionic characteristics.
• Analytical Chemistry: Acts as a high-purity calibrant or standard in chromatographic (HPLC, HPAEC-PAD) and spectroscopic analyses for quality control of alginate products.
