Description

Melacacidin is a naturally occurring flavonoid compound belonging to the class of flavan-3,4-diols (leucoanthocyanidins). This specialized phytochemical is valued for its role as a key biosynthetic precursor and its inherent biological properties. It is primarily utilized in research and development within the phytochemical, nutraceutical, and cosmetic ingredient sectors. Melacacidin CAS NO 38081-16-2 is of particular interest for studies in plant biochemistry and natural product synthesis.

Application

• Phytochemical Reference Standard: Serves as a high-purity analytical standard for the identification and quantification of leucoanthocyanidins in plant extracts and botanical products.
• Nutraceutical Research: Investigated for its potential antioxidant properties and as a precursor in the study of condensed tannin (proanthocyanidin) formation in dietary supplements.
• Cosmetic Ingredient Development: Explored in skincare formulations for its potential antioxidant and skin-conditioning benefits derived from its polyphenolic structure.
• Plant Biochemistry Studies: Used in research to understand the biosynthetic pathways of flavonoids and tannins in various plant species.
• Natural Product Synthesis: Acts as a chiral building block or intermediate in the synthetic chemistry of complex polyphenolic compounds.

Quality Control

Our Melacacidin is produced and handled under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity assessment and spectroscopic methods (NMR, MS) for structural confirmation, to ensure identity, potency, and consistency. A Certificate of Analysis (COA) detailing all relevant specifications is provided with every shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is easily oxidized (store under inert atmosphere) and is light-sensitive (store away from light). For long-term storage, consider sealing under an inert gas such as nitrogen or argon.
