Compared with other compounds in its class, the molecular weight of 400.31 g/mol gives 4-Bromo-4’-(diphenylamino)biphenyl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Bromo-4’-(diphenylamino)biphenyl (CAS 202831-65-0), molecular formula C24H18BrN and molecular weight 400.31 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-Bromo-4’-(diphenylamino)biphenyl (C24H18BrN) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 400.31 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
