Chemical Structure
Description
(E)-2-Methoxy-4-(3-methyl-5-(prop-1-en-1-yl)benzofuran-2-yl)phenol (CAS 41744-28-9) is a high-purity analytical reference standard with the molecular formula C19H18O3 and a molecular weight of 294.34 g/mol.
(E)-2-Methoxy-4-(3-methyl-5-(prop-1-en-1-yl)benzofuran-2-yl)phenol (C19H18O3) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
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.
