Chemical Structure
Description
8-(2-(4-Bromobenzylidene)hydrazinyl)-7-ethyl-1,3-dimethyl-3,7-dihydro-1H-purine-2,6-dione (C16H17BrN6O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine 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.
8-(2-(4-Bromobenzylidene)hydrazinyl)-7-ethyl-1,3-dimethyl-3,7-dihydro-1H-purine-2,6-dione (CAS 374916-08-2), molecular formula C16H17BrN6O2 and molecular weight 405.25 g/mol, is a CATO reference standard with documented purity and traceability.
