Chemical Structure
Description
As a certified reference material (CRM), 1-(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.
1-(3-Bromophenyl)naphthalene (CAS 853945-53-6), molecular formula C16H11Br and molecular weight 283.16 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
