Chemical Structure
Description
The molecular framework of 2-(3-Bromophenyl)naphthalene (C16H11Br) 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).
2-(3-Bromophenyl)naphthalene (CAS 667940-23-0) is a high-purity analytical reference standard with the molecular formula C16H11Br and a molecular weight of 283.16 g/mol.
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.
As a certified reference material (CRM), 2-(3-Bromophenyl)naphthalene 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.
