21H,23H-Porphine, 5,15-bis(4-bromophenyl)-10,20-diphenyl- (CAS 401901-10-8), molecular formula C44H28Br2N4 and molecular weight 772.53 g/mol, is a CATO reference standard with documented purity and traceability.
21H,23H-Porphine, 5,15-bis(4-bromophenyl)-10,20-diphenyl- (C44H28Br2N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
