Description
(19S)-7-(2-aminoethoxy)-10,19-diethyl-19-hydroxy-17-oxa-3,13-diazapentacyclo[11.8.0.0²¹¹.0⁴⁹.0¹⁵²º]henicosa-1(21),2,4,6,8,10,15(20)-heptaene-14,18-dione (C24H25N3O5) contains a flavonoid 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.
