            • • Product Overview

                cis-Resveratrol is a naturally occurring geometrical isomer of resveratrol found in various plants and plant-derived products. It is the less abundant but biologically significant isomer of resveratrol and serves as an important reference standard for the quality control of stilbene-containing products.

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

                Synthetic Process

                cis-Resveratrol can be obtained through photoisomerization of trans-resveratrol or isolation from plant sources:

                1. Photoisomerization: trans-Resveratrol is irradiated with UV light to convert it to the cis-isomer.

                2. Isolation: Extracted from plants that naturally contain cis-resveratrol.

                3. Purification: Preparative HPLC yields the pure cis-isomer.

                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 identification and quantification of resveratrol isomers in plant extracts.

                • Quality Control: Used in the quality assessment of herbal products.

                • Natural Product Chemistry: Serves as a reference for stilbene isomer identification.

                • Method Development: Used in HPLC method validation for isomer separation.
