Chemical Structure
Description
2-tert-Butyl 7-methyl 5-iodo-3,4-dihydroisoquinoline-2,7(1H)-dicarboxylate (C16H20INO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution. Halogen substitution raises its density and boiling point, 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.
