Chemical Structure
Description
The occurrence of 1-Bromo-7-fluoronaphthalene is closely related to fluorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-Bromo-7-fluoronaphthalene (CAS 13790-91-5) is a high-purity analytical reference standard with the molecular formula C10H6BrF and a molecular weight of 225.06 g/mol.
Based on its molecular formula C10H6BrF, 1-Bromo-7-fluoronaphthalene contains fluorine/bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 225.06 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
As a certified reference material (CRM), 1-Bromo-7-fluoronaphthalene 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.
