Compared with other compounds in its class, the molecular weight of 332.96 g/mol gives 1-Bromo-4-iodonaphthalene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-Bromo-4-iodonaphthalene (CAS 63279-58-3), molecular formula C10H6BrI and molecular weight 332.96 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-Bromo-4-iodonaphthalene (C10H6BrI) is characterized by bromine/iodine substitution, an aromatic ring system. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 1-Bromo-4-iodonaphthalene 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.
