6-(4-Methoxyphenyl)-13,15-dioxa-5,9-diazatetracyclo[8.7.0.0^{2,7}.0^{12,16}]heptadeca-1(10),2(7),3,5,8,11,16-heptaene (C20H14N2O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
