Description

cis-Vitisin B is a specialized stilbenoid compound, a derivative of resveratrol oligomers found in grapevines. This high-purity reference standard is critical for analytical research, quality control, and the development of nutraceutical and pharmaceutical products. It serves as an essential tool for researchers and quality assurance professionals in the dietary supplement, natural product, and life science industries seeking to study or standardize complex polyphenol mixtures.

Application

• Analytical Reference Standard: Primary use as a high-purity calibrant for HPLC, LC-MS, and other chromatographic methods in quality control laboratories.
• Phytochemical and Natural Product Research: Investigation of the biological activity, metabolism, and pharmacokinetics of resveratrol-derived oligomers.
• Dietary Supplement Authentication: Used to verify the presence and quantify the content of specific stilbenoids in grape seed extract, red wine extract, and other botanical supplements.
• Pharmaceutical Development: Serves as a starting material or intermediate for the research into novel therapeutics targeting oxidative stress and inflammation.
• Academic and Institutional Research: Fundamental studies in plant biochemistry, polyphenol chemistry, and the health benefits associated with wine and grape constituents.

Quality Control

Our cis-Vitisin B is produced under a rigorous quality management system. Each batch is characterized and tested to ensure identity, purity, and consistency, meeting the stringent requirements for analytical reference materials. A comprehensive Certificate of Analysis (COA) detailing purity by HPLC, identification by spectroscopic methods (NMR, MS), and other relevant parameters is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below under an inert atmosphere for long-term stability. This compound is easily oxidized (store under inert atmosphere) and light-sensitive (store away from light). Allow the sealed container to reach room temperature before opening to prevent moisture condensation.
