Chemical Structure
Description
4,5-Diphenyl-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-imidazole-2-carbaldehyde (C22H26N2O2Si) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
