7-Bromo-12-(naphthalen-2-yl)tetraphene (CAS 1326240-02-1), molecular formula C28H17Br and molecular weight 433.34 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 7-Bromo-12-(naphthalen-2-yl)tetraphene (C28H17Br) is characterized by bromine substitution, a polycyclic aromatic 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 7-Bromo-12-(naphthalen-2-yl)tetraphene 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.
