Chemical Structure
Description
2-(2,4-Dioxo-1,3-diazaspiro[4.5]Decan-3-yl)-N-(4-fluorophenyl)acetamide (C16H18FN3O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, 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.
2-(2,4-Dioxo-1,3-diazaspiro[4.5]Decan-3-yl)-N-(4-fluorophenyl)acetamide (CAS 771503-08-3) is a high-purity analytical reference standard with the molecular formula C16H18FN3O3 and a molecular weight of 319.33 g/mol.
