Chemical Structure

1'-(2-Chloroacetyl)-3',4'-dihydro-1'h-spiro[cyclopentane-1,2'-quinoxaline]-3'-one CAS 878259-34-8 chemical structure

Description

1'-(2-Chloroacetyl)-3',4'-dihydro-1'h-spiro[cyclopentane-1,2'-quinoxaline]-3'-one (C14H15ClN2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.
