Chemical Structure
Description
The occurrence of N,N-Bis(4-bromophenyl)-4-biphenylamine 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.
N,N-Bis(4-bromophenyl)-4-biphenylamine (CAS 884530-69-2) is a high-purity analytical reference standard with the molecular formula C24H17Br2N and a molecular weight of 479.21 g/mol.
The molecular framework of N,N-Bis(4-bromophenyl)-4-biphenylamine (C24H17Br2N) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), N,N-Bis(4-bromophenyl)-4-biphenylamine 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.
