Chemical Structure
Description
N,N-Bis(4-biphenylyl)-N-(4-bromophenyl)amine (CAS 499128-71-1), molecular formula C30H22BrN and molecular weight 476.41 g/mol, is a CATO reference standard with documented purity and traceability.
N,N-Bis(4-biphenylyl)-N-(4-bromophenyl)amine (C30H22BrN) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
