Chemical Structure
Description
The occurrence of 1-Benzyl-2,3,4,5,6-pentaphenylpyridin-1-ium bromide is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-Benzyl-2,3,4,5,6-pentaphenylpyridin-1-ium bromide (CAS 71140-67-5), molecular formula C42H32NBr and molecular weight 630.63 g/mol, is a CATO reference standard with documented purity and traceability.
1-Benzyl-2,3,4,5,6-pentaphenylpyridin-1-ium bromide (C42H32NBr) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine 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.
