Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1-(4-Bromophenyl)-2-(triphenyl-l5-phosphaneylidene)ethan-1-one (CAS 1777-57-7) is a high-purity analytical reference standard with the molecular formula C10H19ClN2O and a molecular weight of 218.72 g/mol.
1-(4-Bromophenyl)-2-(triphenyl-l5-phosphaneylidene)ethan-1-one (C10H19ClN2O) contains an amide group, a hydroxyl group, an ether linkage, 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.
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.
