Chemical Structure
Description
8-Bromo-2-fluoro-6-methoxynaphthalen-1-yl trifluoromethanesulfonate (CAS 2757097-46-2) is a high-purity analytical reference standard with the molecular formula C12H7BrF4O4S and a molecular weight of 403.14 g/mol.
Based on its molecular formula C12H7BrF4O4S, 8-Bromo-2-fluoro-6-methoxynaphthalen-1-yl trifluoromethanesulfonate contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 403.14 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
