Description
As a certified reference material (CRM), N,N-Bis(4-bromophenyl)-2,4-dimethylphenylamine 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.
N,N-Bis(4-bromophenyl)-2,4-dimethylphenylamine (CAS 157913-52-5) is a high-purity analytical reference standard with the molecular formula C20H17Br2N and a molecular weight of 431.16 g/mol.
N,N-Bis(4-bromophenyl)-2,4-dimethylphenylamine (C20H17Br2N) 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 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.
