The occurrence of Fluorescent Brightener 85 is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Fluorescent Brightener 85 (CAS 12224-06-5), a certified reference material (molecular formula C36H34N12O8S2Na, MW 849.85 g/mol) for analytical method development and quality control.
Fluorescent Brightener 85 (C36H34N12O8S2Na) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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.
