4-[(3-Methoxyphenyl)methoxy]-3,4-dihydro-2H-1-benzopyran (CAS 866155-73-9), molecular formula C17H18O3 and molecular weight 270.32 g/mol, is a CATO reference standard with documented purity and traceability.
4-[(3-Methoxyphenyl)methoxy]-3,4-dihydro-2H-1-benzopyran (C17H18O3) 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.
CATO manufactures 4-[(3-Methoxyphenyl)methoxy]-3,4-dihydro-2H-1-benzopyran under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
