Description

2',3,4',5,5',6,7,8-Octamethoxyflavone is a highly substituted polymethoxyflavone (PMF), a distinct subclass of flavonoids known for their potent biological activities. This compound matters for its role as a key reference standard and active pharmaceutical ingredient (API) intermediate in research and development. It is primarily needed by pharmaceutical R&D laboratories, nutraceutical manufacturers, and academic institutions focused on studying bioactive natural products for therapeutic applications.

Application

• Pharmaceutical Reference Standard: Used for the qualitative and quantitative analysis (HPLC, LC-MS) of polymethoxyflavones in drug discovery and quality control laboratories.
• Bioactive Compound Research: Serves as a crucial intermediate or lead compound in pharmacological studies investigating anti-inflammatory, antioxidant, and neuroprotective effects.
• Nutraceutical Development: Employed in the formulation and standardization of high-value dietary supplements derived from citrus or other plant sources rich in PMFs.
• Chemical Synthesis: Acts as a sophisticated building block or precursor for the semi-synthesis of novel flavonoid derivatives with enhanced bioactivity.
• Academic & Institutional Research: Utilized in universities and research institutes for fundamental studies on flavonoid chemistry, metabolism, and structure-activity relationships (SAR).
