Oxyresveratrol CAS 29700-22-9 Bulk Supplier | High-Purity Stilbene Antioxidant for Advanced Formulations

Oxyresveratrol (CAS 29700-22-9) is a naturally occurring polyphenolic stilbene compound primarily derived from the heartwood of Morus alba (white mulberry). Supplied as a yellow fine powder with ≥98% purity (HPLC), it is recognized for its potent antioxidant, anti-tyrosinase, and anti-aging properties. Oxyresveratrol serves as a multifunctional bioactive in cosmetics, nutraceuticals, and biomedical research applications.

Product Description

This high-purity compound belongs to the stilbene class, structurally related to resveratrol but with enhanced hydroxylation that increases antioxidant potential and biological activity. Each batch is carefully tested using validated analytical methods, including HPLC for purity, ICP-MS for trace metal screening, and ISO 6579:2002 microbiological testing to ensure compliance with international quality standards. Its stable, fine powder form allows excellent dispersibility and integration into both aqueous and lipid-based systems.
