What is Vitisin B?
Vitisin B (CAS 142449-90-9) is a scarce stilbenoid tetramer relevant to laboratories working on higher-order resveratrol oligomers, identity confirmation, and comparative natural-product chemistry. Because tetrameric records can be confused with related vitisin naming in the literature, a structure-first, documentation-backed supplier record matters for procurement review.
Research Applications
- Higher-order stilbenoid identity work
- Comparative oligomer profiling against vitisin A and viniferins
- Analytical reference support for rare natural-product studies
- Procurement review for scarce tetramer sourcing programs
Product Specifications
Vitisin B is indexed under CAS 142449-90-9 with molecular formula C56H42O12 and molecular weight 906.92 g/mol. The public specification set keeps >=95% (estimated) purity posture, Purple/blue fluorescent solid appearance, and -20C, inert atmosphere, protect from light storage guidance visible so analytical teams can compare this record against adjacent compounds before routing a purchase request. In commercial terms, the material is currently qualified through request-based procurement review, which keeps the public listing aligned with the real RUO sourcing posture.
Documentation
Vitisin B is handled as a quote-led supply program rather than a consumer-style stocked item. Documentation review, lot planning, and qualification are treated as part of the sourcing process for this tetrameric material.
Storage & Handling
Store vitisin B at -20C under inert, low-light conditions and keep exposure to ambient air and bench light as brief as practical during weighing or transfer. Because this is a higher-order oligomer with batch-level stereochemical context, internal chain-of-custody and aliquot notes are recommended whenever the material is being compared across multiple analytical runs.
