Resveratrol 98% Purity Stilbene Standard CAS 501-36-0 Research Grade Reference Standard

• • Product Overview

    Resveratrol (trans-3,4',5-Trihydroxystilbene) is a naturally occurring stilbenoid found in the skin of red grapes, red wine, and various plants including Polygonum cuspidatum. It is one of the most widely studied natural products and serves as an important reference standard for the quality control of grape-derived and botanical products.

    With the molecular formula C₁₄H₁₂O₃ and a molecular weight of 228.24 g/mol, this compound appears as a white to off-white crystalline powder. It is soluble in methanol, ethanol, DMSO, and DMF. The product is supplied at ≥98% purity as determined by HPLC analysis.

    Synthetic Process

    Resveratrol is obtained through isolation from plant sources or by chemical synthesis:

    1. Extraction: Polygonum cuspidatum roots or grape skins are extracted with organic solvents.

    2. Chromatographic Separation: The extract is fractionated using column chromatography.

    3. Purification: Recrystallization or preparative HPLC yields the pure compound.

    4. Identity Confirmation: Structure is confirmed by NMR and mass spectrometry.

    Mechanism of Action & Applications

    This compound is primarily used as:

    • Reference Standard: For the quantification of stilbenoids in wine, grape products, and botanical extracts.
