Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 515.82 g/mol gives 4,4'-Oxybis(2,6-dibromoaniline) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4,4'-Oxybis(2,6-dibromoaniline) (CAS 61381-91-7) is a high-purity analytical reference standard with the molecular formula C12H8Br4N2O and a molecular weight of 515.82 g/mol.
The molecular framework of 4,4'-Oxybis(2,6-dibromoaniline) (C12H8Br4N2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 4,4'-Oxybis(2,6-dibromoaniline) under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
