Chemical Structure
Description
(SP-4-2)-[1,1'-(1,4-butanediyl)bis[1,1-diphenylphosphine-κp]]dichloroplatinum (C28H28Cl2P2Pt) contains organophosphorus functionality, chlorine substitution, a polycyclic aromatic system. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
(SP-4-2)-[1,1'-(1,4-butanediyl)bis[1,1-diphenylphosphine-κp]]dichloroplatinum (CAS 65097-96-3), molecular formula C28H28Cl2P2Pt and molecular weight 692.45 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
