Description

Rhamnogalacturonan As4 is a specific, high-purity polysaccharide derived from pectin, characterized by its unique rhamnogalacturonan-I (RG-I) backbone structure. This compound matters for its role as a bioactive material and a critical standard in analytical and research applications, offering consistent structural integrity for reliable results. It is primarily needed by researchers and manufacturers in the pharmaceutical, nutraceutical, and advanced cosmetic industries, where precise molecular standards are essential for product development and quality control.

Application

• Pharmaceutical Research & Standardization: Serves as a certified reference material (CRM) for the quantification and qualification of pectin-derived polysaccharides in drug formulations and herbal extracts.
• Nutraceutical Development: Used as a bioactive ingredient or a model compound in the research of prebiotic, immunomodulatory, and gut health supplements.
• Cosmetic Science: Employed in R&D for high-end skincare products, studying its moisturizing, film-forming, and skin barrier-enhancing properties.
• Food Science & Technology: Acts as a research standard for analyzing pectin structure-function relationships, gelling mechanisms, and texture modification.
• Academic & Biochemical Research: Essential for studies in plant cell wall biology, carbohydrate chemistry, and enzymology (e.g., pectinase activity assays).
• Quality Control Laboratories: Provides a benchmark for the purity and identity testing of commercial pectin products and related raw materials.

Quality Control

Every batch of Rhamnogalacturonan As4 is produced and tested under strict quality management protocols to ensure it meets the high standards required for research and analytical applications. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request, detailing parameters such as purity, identification, and moisture content.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed in a low-humidity environment to prevent degradation and clumping.
