Description
As a certified reference material (CRM), 4-Bromo-N-(4-bromophenyl)-N-(4-butylphenyl)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.
4-Bromo-N-(4-bromophenyl)-N-(4-butylphenyl)aniline (CAS 276690-04-1), molecular formula C22H21Br2N and molecular weight 459.22 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Bromo-N-(4-bromophenyl)-N-(4-butylphenyl)aniline (C22H21Br2N) 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.
