Chemical Structure
Description
9-Bromo-10-(2-naphthyl)anthracene (CAS 474688-73-8), molecular formula C24H15Br and molecular weight 383.28 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 9-Bromo-10-(2-naphthyl)anthracene (C24H15Br) 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 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 9-Bromo-10-(2-naphthyl)anthracene 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.
