Chemical Structure
Description
2,2'-(((Disulfanediylbis(4,1-phenylene))bis(azanylylidene))bis(methanylylidene))diphenol (CAS 3430-53-3), molecular formula C26H20N2O2S2 and molecular weight 456.58 g/mol, is a CATO reference standard with documented purity and traceability.
2,2'-(((Disulfanediylbis(4,1-phenylene))bis(azanylylidene))bis(methanylylidene))diphenol (C26H20N2O2S2) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2,2'-(((Disulfanediylbis(4,1-phenylene))bis(azanylylidene))bis(methanylylidene))diphenol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
