Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
(2R,3R)-2-(3,4-Dimethoxyphenyl)-7-methoxy-3-methyl-5-((E)-prop-1-en-1-yl)-2,3-dihydrobenzofuran (CAS 41744-39-2) is a high-purity analytical reference standard with the molecular formula C21H24O4 and a molecular weight of 340.41 g/mol.
The molecular framework of (2R,3R)-2-(3,4-Dimethoxyphenyl)-7-methoxy-3-methyl-5-((E)-prop-1-en-1-yl)-2,3-dihydrobenzofuran (C21H24O4) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
