Chemical Structure
Description
Acetic acid 14-[7a-methyl-1-(1,4,5-trimethyl-hex-2-enyl)- octahydro-inden-4-ylidenemethyl]-7,12-dioxo- 1,2,3,4,5,7,12,14-octahydro-phthalazino[2,3-β]phthalazin-2-yl ester (C38H50N2O4) contains a nitrogen-containing heterocyclic scaffold, 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.
