ε-Viniferin

epsilon-Viniferin (CAS 62218-08-0) is a resveratrol dimer in the stilbenoid oligomer class and serves as the clearest dimeric anchor in the launch set. The associated research notes frame it as a useful identity-reviewed benchmark when teams need to compare dimeric viniferins to higher-order oligomers such as alpha-viniferin, vitisin A, and vitisin B, or when they need a structure-first material for HPLC and LC-MS method work.

Each procurement discussion is supported with RUO labeling and document-forward review. COA and SDS access are attached to the product record so analytical teams can confirm identity, purity posture, and basic handling expectations before purchase-order qualification. That documentation-first approach matches the guidance in the reference-standard supplier notes, where CAS visibility, analytical posture, and downloadable support materially reduce friction for institutional review.

Store epsilon-viniferin sealed at -20C under an inert atmosphere and protected from light to support identity-sensitive analytical work. For routine laboratory use, allow the container to equilibrate before opening, minimize repeated warm-up cycles, and document aliquot history when the compound is being used as a comparative standard across longer method-development campaigns.
