Chemical Structure
Description
Os(4,4′-Dimethyl-2,2′-bipyridine)2Cl2 (CAS 238759-94-9) is a high-purity analytical reference standard with the molecular formula C24H24Cl2N4OsCl and a molecular weight of 665.06 g/mol.
Os(4,4′-Dimethyl-2,2′-bipyridine)2Cl2 (C24H24Cl2N4OsCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
