Chemical Structure
Description
Ethyl 7-(4-methoxy-3,5-dimethylphenyl)-7-oxoheptanoate (C18H26O4) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Ethyl 7-(4-methoxy-3,5-dimethylphenyl)-7-oxoheptanoate (CAS 898751-10-5), molecular formula C18H26O4 and molecular weight 306.40 g/mol, is a CATO reference standard with documented purity and traceability.
