Description

Vitisin A CAS NO 142449-89-6 is a specialized stilbenoid compound, a member of the viniferin family, known for its significant biological activity. This high-purity reference standard is critical for research and development in the nutraceutical and pharmaceutical sectors, where precise compound characterization is paramount. It is primarily sought by analytical laboratories, R&D departments, and manufacturers focused on natural product extraction and standardization for health-promoting formulations.

Application

• Pharmaceutical Reference Standard: Used as a certified reference material (CRM) for the identification, purity assessment, and quantification of Vitisin A in drug substances and finished products.
• Nutraceutical Research: Serves as a key analytical standard in the development and quality control of dietary supplements derived from grapevine (Vitis vinifera) extracts, such as those from grape seeds or vine shoots.
• Academic & Biomedical Research: Employed in in vitro and in vivo studies to investigate its potential antioxidant, anti-inflammatory, and cardioprotective properties.
• Cosmeceutical Ingredient Analysis: Acts as a marker compound for the standardization and authentication of cosmetic ingredients claiming benefits from grape-derived polyphenols.
• Food & Beverage Science: Utilized in the analysis of complex phenolic profiles in wines, grape juices, and other plant-based beverages to study quality and authenticity.
• Method Development & Validation: Essential for developing and validating analytical methods (e.g., HPLC, LC-MS) for stilbenoid detection and quantification in various matrices.
