Chemical Structure
Description
The molecular framework of Ruthenate(4-), di-μ-chlorodichlorotetrakis[3-(diphenylphosphino-κP)benzenesulfonato]di-, tetrasodium (C72H56Cl4O12P4Ru2S4Na) is characterized by a salt form, a sulfone group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Ruthenate(4-), di-μ-chlorodichlorotetrakis[3-(diphenylphosphino-κP)benzenesulfonato]di-, tetrasodium (CAS 187026-26-2), molecular formula C72H56Cl4O12P4Ru2S4Na and molecular weight 1732.29 g/mol, is a CATO reference standard with documented purity and traceability.
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), Ruthenate(4-), di-μ-chlorodichlorotetrakis[3-(diphenylphosphino-κP)benzenesulfonato]di-, tetrasodium meets the metrological traceability requirements of ISO/IEC 17025 laboratories.
