Vitisin A

Vitisin A (CAS 142449-89-6) is a tetrameric resveratrol oligomer relevant to laboratories studying higher-order stilbenoid identity, comparative oligomer chemistry, and rare natural-product reference materials. The chemistry-note comparison page treats it as a higher-order record that benefits from explicit structural context because tetrameric members of the family share broad naming patterns while remaining chemically distinct.

Vitisin A is handled as a made-to-order procurement path with documentation review and scheduling support. COA and SDS access remain part of the public record so research teams can evaluate the material before committing to a batch plan. That approach follows the supplier-evaluation guidance already published in the research library, where rare materials are expected to show identity, document posture, and honest lead-time framing before procurement advances.

Store vitisin A at -20C with protection from light and ambient moisture, and keep sample exposure brief during dispensing so higher-order oligomer handling remains consistent from lot to lot. For laboratories using the compound as a tetrameric comparison standard, it is good practice to record aliquot history, storage deviations, and document references directly in the analytical file.
