Description

α-Viniferin is a naturally occurring oligostilbene compound, a dimer of resveratrol, known for its potent biological activities. Its significance lies in its strong antioxidant and anti-inflammatory properties, making it a valuable reference standard and a promising candidate for research into nutraceuticals and pharmaceuticals. This high-purity compound is essential for researchers and manufacturers in the pharmaceutical, cosmetic, and dietary supplement industries who require a reliable, well-characterized material for analytical, development, and formulation work.

Application

• Pharmaceutical Research & Development: Used as a high-purity reference standard and active pharmaceutical ingredient (API) intermediate for studying anti-inflammatory, antioxidant, and neuroprotective effects.
• Nutraceutical & Dietary Supplement Formulation: Incorporated as a key bioactive component in supplements targeting oxidative stress and metabolic health, leveraging its resveratrol-enhancing properties.
• Cosmeceutical Product Development: Serves as a potent anti-aging and skin-protecting agent in advanced serums, creams, and lotions due to its strong antioxidant capacity.
• Analytical & Bioassay Standards: Critical for quality control (QC) and method development in laboratories for the quantification of stilbenes in plant extracts and finished products.
• Academic & Preclinical Studies: Employed in biochemical and pharmacological research to investigate mechanisms of action related to chronic diseases, cancer, and longevity pathways.

Quality Control

Our α-Viniferin is produced and tested under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles. We adhere to relevant industry standards for reference materials, and specifications can be tailored to meet specific research or cGMP starting material requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C under an inert atmosphere (e.g., nitrogen or argon) to minimize oxidation. Keep the container tightly sealed in a desiccator to protect from moisture. For long-term storage, consider freezing at -20°C.
