Sodium (SP-4-1)-[29H,31H-phthalocyanine-2,9,16,23-tetrasulfonato(6-)-κN29,κN30,κN31,κN32]ferrate (CAS 41867-66-7), molecular formula C32H12FeN8O12S4Na and molecular weight 907.57 g/mol, is a CATO reference standard with documented purity and traceability.
Sodium (SP-4-1)-[29H,31H-phthalocyanine-2,9,16,23-tetrasulfonato(6-)-κN29,κN30,κN31,κN32]ferrate (C32H12FeN8O12S4Na) 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
