Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 249.16 g/mol gives 3-bromo-1-fluoro-8-methyl-naphthalene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-bromo-1-fluoro-8-methyl-naphthalene (CAS 2387595-55-1) is a high-purity analytical reference standard with the molecular formula C11H18BrF and a molecular weight of 249.16 g/mol.
3-bromo-1-fluoro-8-methyl-naphthalene (C11H18BrF) contains fluorine/bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
