4-Bromo-N-(4-bromophenyl)-N-(4-(sec-butyl)phenyl)aniline (CAS 860495-17-6) is a high-purity analytical reference standard with the molecular formula C22H21Br2N and a molecular weight of 459.22 g/mol.
Structurally, 4-Bromo-N-(4-bromophenyl)-N-(4-(sec-butyl)phenyl)aniline (C22H21Br2N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 459.22 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), 4-Bromo-N-(4-bromophenyl)-N-(4-(sec-butyl)phenyl)aniline meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
