CATO supplies 1,1'-(((Sulfonylbis(4,1-phenylene))bis(oxy))bis(4,1-phenylene))bis(1H-pyrrole-2,5-dione) (CAS 56166-52-0), a certified reference material (molecular formula C32H20N2O8S, MW 592.57 g/mol) for analytical method development and quality control.
1,1'-(((Sulfonylbis(4,1-phenylene))bis(oxy))bis(4,1-phenylene))bis(1H-pyrrole-2,5-dione) (C32H20N2O8S) 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.
CATO manufactures 1,1'-(((Sulfonylbis(4,1-phenylene))bis(oxy))bis(4,1-phenylene))bis(1H-pyrrole-2,5-dione) under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
