Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 283.16 g/mol gives 1-Bromo-2-phenylnaphthalene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1-Bromo-2-phenylnaphthalene (CAS 22082-93-5), a certified reference material (molecular formula C16H11Br, MW 283.16 g/mol) for analytical method development and quality control.
The molecular framework of 1-Bromo-2-phenylnaphthalene (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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
