4,6-Dimethoxy-2-methyl-3-(p-tolyl)benzofuran (CAS 922140-81-6) is a high-purity analytical reference standard with the molecular formula C18H18O3 and a molecular weight of 282.33 g/mol.
4,6-Dimethoxy-2-methyl-3-(p-tolyl)benzofuran (C18H18O3) 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.
