Used in research as a methylated derivative of flavellagic acid, this compound serves as a reference standard in phytochemical studies, particularly in the analysis of tannins and ellagitannin metabolites. Its modified structure enhances stability and solubility, making it suitable for chromatographic and mass spectrometric applications. It is also employed in metabolic pathway investigations to trace the transformation of polyphenolic compounds in biological systems. Due to the methylenedioxy and methyl group protections, it aids in structure-activity relationship studies of antioxidant and enzyme-inhibiting natural products.
