Chemical Structure
Description
(SP-4-2)-Dibromo[1,2-ethanediylbis[diphenylphosphine-κP]]-Nickel (C26H24Br2NiP2) contains organophosphorus functionality, bromine 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
(SP-4-2)-Dibromo[1,2-ethanediylbis[diphenylphosphine-κP]]-Nickel (CAS 14647-21-3), molecular formula C26H24Br2NiP2 and molecular weight 616.92 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.
